When a government minister leaves office and joins a company in the sector they regulated, is that a coincidence or a reward? When a Prime Minister earns more in a single year of private consultancy than in a decade of public service, has the system worked as intended? When a sitting MP receives £100,000 a year from a company that then wins £500 million in government contracts, should the public be concerned?
This report forensically examines the personal financial interests of current and former UK politicians and senior officials — the revolving door between government and industry, second jobs held while serving, shareholdings in regulated sectors, and the post-office enrichment of former Prime Ministers. It maps the regulatory framework designed to prevent conflicts of interest and asks a simple question: does it work?
Every name, role, company, fee, and appointment cited in this report is drawn from public records: the Register of Members’ Financial Interests, ACOBA published decisions, Companies House filings, official parliamentary inquiry reports, and verified investigative journalism. The findings are not allegations — they are the documented facts of a system that permits, and in many cases encourages, the enrichment of public servants by private interests.
Between 2017 and 2022, ACOBA reviewed 604 post-government appointments. Of these, 177 (29%) involved individuals taking roles with significant policy overlap — the private role was directly connected to the area of government they had overseen. In the defence sector, the overlap rate was 81%. ACOBA has zero enforcement powers. It cannot block an appointment, impose a fine, or refer a breach for prosecution. Its maximum sanction is a published letter. ACOBA has less power than a parking attendant.
David Cameron sent 56+ messages to serving ministers, including nine to Chancellor Rishi Sunak, lobbying for Greensill Capital’s access to public lending facilities. Cameron held share options reportedly worth up to £60 million. Greensill had already been embedded in government since 2011 as an unpaid adviser with a Downing Street desk, then as a Crown Representative with access to 11 departments. The company secured approximately £400 million in government-backed loans before collapsing in March 2021. The Treasury Select Committee found a “significant lack of judgment.” The Boardman Inquiry confirmed governance failures. No individual faced any legal consequence.
The regulatory framework for post-government employment, second jobs, and lobbying exists on paper but lacks any meaningful enforcement mechanism. ACOBA can advise but cannot enforce, fine, or prosecute. The cooling-off period is advisory and unmonitored. The Register of Members’ Financial Interests relies on self-declaration. The Transparency of Lobbying Act 2014 covers only consultant lobbyists, missing the vast majority of lobbying activity. When Philip Hammond breached ACOBA advice by taking a Saudi advisory role early, the sanction was a letter. When he breached again with Copper.co, the sanction was another letter.
Nine individual case studies. The revolving door master table. 330 MPs with second jobs. Six layers of enrichment. Reform proposals. 12 verified sources.

The UK’s framework for managing conflicts of interest rests on three pillars: the Advisory Committee on Business Appointments (ACOBA), the Register of Members’ Financial Interests, and a set of cooling-off conventions. Each pillar is structurally compromised.
Established in 1975, ACOBA is a non-statutory advisory body that reviews post-government appointments for former ministers and senior civil servants. It was created by convention, not by Act of Parliament, meaning it has no legal authority to compel compliance. Its recommendations are advisory. It cannot block an appointment, impose a fine, delay a start date, or refer a breach for investigation. When its advice is ignored, the maximum sanction is a published letter expressing displeasure — placed on the ACOBA website, typically weeks or months after the appointment has already been taken up.
ACOBA does not monitor whether the conditions it attaches to approvals are actually followed. It has no compliance team, no investigative capacity, and no mechanism for proactive oversight. Its entire staff is a small secretariat within the Cabinet Office — the very department whose former officials it is nominally overseeing. The Committee on Standards in Public Life, Transparency International UK, and multiple House of Commons Select Committees have recommended that ACOBA be placed on a statutory footing with enforcement powers. As of March 2026, no government of any party has implemented these recommendations.
The Register is the primary mechanism through which MPs declare their outside earnings, directorships, shareholdings, gifts, and hospitality. It operates on a self-declaration basis: MPs are required to register interests within 28 days under the House of Commons Code of Conduct. There is no independent verification of declarations. The Parliamentary Commissioner for Standards can investigate complaints, but only acts on receipt of a specific complaint — there is no routine audit, no random sampling, and no cross-referencing with Companies House records.
In the parliamentary year 2020–21, approximately 330 MPs declared paid outside employment or advisory roles, with total declared earnings estimated at £5.5 million. This figure may understate the true total, as the Register captures only those interests that MPs choose to declare, and the enforcement of declaration obligations relies on a complaints-based system with limited investigative resources.
The Ministerial Code and the Business Appointment Rules specify a cooling-off period of up to two years after leaving government, during which former ministers and senior civil servants should seek ACOBA advice before taking up outside employment. The period is notionally designed to prevent the immediate transfer of insider knowledge, contacts, and influence to private employers. In practice, the cooling-off period is advisory, unmonitored, and routinely circumvented. ACOBA cannot extend it, cannot enforce it, and does not verify compliance. Former ministers are free to ignore ACOBA’s advice entirely. When they do, the consequence is a letter.
Eight years later, Cameron joined Greensill Capital with share options worth up to £60 million.
The body that is supposed to prevent conflicts of interest has no power to prevent anything. Understanding ACOBA is understanding why the revolving door remains open.
| Established | 1975 |
| Chair | Lord Pickles (as of 2026) |
| Legal Status | Non-statutory advisory body — exists by convention, not by law |
| Enforcement Powers | None — cannot block appointments, impose fines, or refer for prosecution |
| Sanction for Breach | A letter — published on the ACOBA website |
| Compliance Monitoring | None — ACOBA does not monitor whether its conditions are followed |
| Cooling-off Period | Up to 2 years (advisory only — cannot be enforced) |
| Budget | Minimal — staffed by a small Cabinet Office secretariat |
Between 2017 and 2022, ACOBA reviewed 604 post-government appointments. Of these, 177 (29%) involved individuals taking roles with significant policy overlap — meaning the private role was directly connected to the area of government they had overseen. In the defence sector, the overlap rate was 81%. In energy, 52%. In financial services, 47%.
ACOBA approved the vast majority of applications. In cases where it recommended a waiting period or conditions, it had no mechanism to verify compliance. In the cases of Philip Hammond (Saudi advisory role) and Bill Crothers (Greensill), ACOBA confirmed breaches — but the sanction in both cases was a published letter. No fine. No referral. No consequence beyond reputational.
Lord Pickles, ACOBA’s own chair, has publicly stated that the committee needs statutory powers. In evidence to the Public Administration and Constitutional Affairs Committee in 2021, Pickles said the system was “not fit for purpose” without legal backing. The Government declined to legislate.
The Committee on Standards in Public Life, Transparency International UK, and multiple House of Commons Select Committees have recommended that ACOBA be placed on a statutory footing with enforcement powers. As of March 2026, none of these recommendations have been implemented by any government of any party.
Nine documented cases illustrating the pattern of post-office enrichment, revolving door appointments, and regulatory failure. Every fact is drawn from public records.
Within the same month of leaving Downing Street in June 2007, Tony Blair was appointed as a senior adviser to JP Morgan, at a reported fee of over £2 million per year. JP Morgan is one of the world’s largest investment banks, with extensive involvement in UK infrastructure finance, PFI deals, and government bond markets — all areas shaped by policy decisions during Blair’s decade in office.
Blair also established Tony Blair Associates (TBA), a private consultancy that provided strategic advice to sovereign clients including the governments of Kazakhstan and Kuwait. TBA’s activities were structured through a complex web of entities that made full financial disclosure difficult to establish from public records alone. Estimated total post-office earnings range from £30 million to £60 million.
In 2008, Blair’s involvement with UI Energy Corporation — a company with oil interests in Iraq, the country he had led the UK to war with in 2003 — emerged through investigative journalism. Blair’s office had requested that his connection to the company not be publicly disclosed.
Blair’s domestic policy legacy compounds the concern. His government’s expansion of the Private Finance Initiative (PFI) committed future taxpayers to payments exceeding £10 billion per year for decades. Hospitals and schools built under PFI have cost the public between two and seven times their original construction value. The National Audit Office has repeatedly questioned the value for money of PFI contracts — contracts from which the financial institutions Blair subsequently joined profited substantially.
The Cameron-Greensill case is the most thoroughly documented example of the revolving door in modern British politics, subject to two official inquiries (Boardman, 2021; Treasury Select Committee, 2021) and extensive parliamentary scrutiny. The timeline reveals a relationship between government and private interest that spans a decade.
The Treasury Select Committee found that Cameron had shown a “significant lack of judgment” and that the rules governing lobbying by former Prime Ministers were “too weak to capture” his activities. The Boardman Inquiry confirmed multiple failures of governance in the appointment of Greensill as a Crown Representative, the lack of proper records, and the absence of transparency in Cameron’s lobbying activities.
The Boardman Inquiry also found that the Chief Commercial Officer, Bill Crothers, had begun working for Greensill while still a serving civil servant — a fact never disclosed to his superiors (see Case 8 below).
Within five months of leaving the Treasury, George Osborne accepted a position as a senior adviser to BlackRock, the world’s largest asset manager, at a reported salary of £650,000 per year for one day per week. BlackRock manages assets exceeding £7 trillion globally and holds significant stakes in privatised UK utilities and infrastructure — including water companies, energy firms, and transport operators whose regulatory and fiscal framework Osborne had shaped as Chancellor.
The appointment was approved by ACOBA with a condition that Osborne should not draw on privileged information from his time in government. ACOBA had no mechanism to monitor or enforce this condition.
In the five years following his departure from government, Osborne accumulated more than ten private-sector roles, including:
The Evening Standard appointment was particularly notable. Osborne took the editorship without seeking ACOBA clearance, a confirmed breach of the Business Appointment Rules. ACOBA wrote a letter. Osborne continued as editor. The Evening Standard subsequently ran extensive coverage of London’s infrastructure programme — which Osborne had helped shape as Chancellor — including the Northern Powerhouse initiative he had championed.
Philip Hammond left the Treasury in July 2019. Within eight months, he accepted an advisory role with a Saudi Arabian entity. ACOBA had advised a longer cooling-off period, but Hammond commenced the role before the advised period had elapsed. ACOBA confirmed the breach.
In a subsequent case, Hammond took up a role as an adviser to Copper.co, a cryptocurrency firm, without seeking ACOBA clearance. This was a second confirmed breach of the Business Appointment Rules. ACOBA again wrote a letter, published on its website. Hammond continued in the role.
Hammond also established Hammond McNally Ltd, a private consultancy through which he channels advisory fees. Companies House filings indicate the company has generated turnover of approximately £1 million per year since its incorporation. As Chancellor, Hammond had overseen UK financial regulation, tax policy, and the Treasury’s approach to fintech and cryptocurrency — precisely the sectors in which he subsequently took private advisory roles.
The Hammond case is significant not for the individual sums involved, but for what it reveals about enforcement. A former Chancellor of the Exchequer breached ACOBA advice twice, in documented and confirmed instances, and the total consequence was two published letters. No fine. No referral. No restriction on future appointments. No sanction of any kind beyond reputational.
Owen Paterson is the most serious case documented in this report because the conflict was not post-office — it was concurrent. While serving as a sitting Member of Parliament, Paterson received approximately £100,000 per year from Randox Laboratories and a further sum from Lynn’s Country Foods, both declared on the Register of Members’ Financial Interests. The payments were legal under existing rules. What was not legal was what Paterson did with the access those payments bought.
The Parliamentary Commissioner for Standards, Kathryn Stone, found that Paterson had made 14 approaches to the Food Standards Agency (FSA) on behalf of Randox and Lynn’s Country Foods between 2016 and 2020. These approaches constituted “egregious” paid advocacy — using his position as a Member of Parliament to lobby government bodies on behalf of companies that were paying him. The Commissioner recommended a 30-day suspension from the House of Commons.
Randox Laboratories subsequently received approximately £500 million in Covid-19 testing contracts through the Government’s VIP lane — a procurement channel through which contracts were awarded to companies referred by ministers, MPs, and senior officials. Paterson’s referral of Randox to the VIP lane was documented by the National Audit Office.
When the Standards Committee recommended Paterson’s suspension, the Government whipped Conservative MPs to vote against it and attempted to replace the independent standards process with a new committee chaired by a Conservative MP. The vote succeeded 250–232, but a public outcry forced a reversal within 24 hours. Paterson resigned his seat. A by-election in North Shropshire — a Conservative stronghold since 1832 — was won by the Liberal Democrats with a 34-point swing.
Mark Sedwill served as Cabinet Secretary and Head of the Civil Service from 2018 to 2020 — the most senior official in the UK government. He previously served as National Security Adviser, overseeing intelligence, defence, and foreign policy. As Cabinet Secretary, he had access to the most sensitive information across every government department, including procurement, defence contracts, and financial policy.
After leaving government, Sedwill was appointed as a Non-Executive Director of BAE Systems — the UK’s largest arms company and one of the government’s most significant defence contractors. BAE Systems holds billions of pounds in active UK defence contracts. Sedwill was also appointed as a Senior Adviser to Rothschild & Co, the investment bank that has advised the UK government on major transactions including privatisations, infrastructure sales, and sovereign debt management for decades.
Both appointments were submitted to ACOBA and approved with standard conditions. ACOBA had no mechanism to monitor compliance with those conditions. The appointments were lawful and procedurally correct under existing rules.
Theresa Villiers served as Secretary of State for Environment, Food and Rural Affairs from July 2019 to February 2020. Throughout her tenure, she held shares in Royal Dutch Shell worth approximately £70,000, as declared on the Register of Members’ Financial Interests. Shell is one of the world’s largest fossil fuel companies and a major subject of environmental policy, climate regulation, and energy transition decisions — all of which fell within Villiers’ ministerial responsibilities.
The shareholding was legal. It was declared. It complied with the Ministerial Code and the House of Commons Code of Conduct. Under existing rules, ministers are not required to divest shareholdings in companies operating in their policy area, provided the holding is declared.
The Villiers case is included in this report not because it represents a breach of rules, but because it illustrates what the rules permit. A Secretary of State with direct responsibility for environmental policy — including the UK’s approach to fossil fuels, net zero commitments, and environmental regulation — was allowed to hold a financial interest in one of the world’s largest fossil fuel companies throughout her time in office.
Bill Crothers served as the Government’s Chief Commercial Officer from 2012 to 2015, responsible for overseeing billions of pounds in public procurement. The Boardman Inquiry, commissioned by the Prime Minister in the wake of the Greensill collapse, found that Crothers had begun working as an adviser to Greensill Capital while he was still a serving civil servant.
Crothers did not disclose the Greensill relationship to his superiors. He did not seek ACOBA clearance before commencing the role. The arrangement was discovered by the Boardman Inquiry team through document review, not through any regulatory process or self-declaration. The Boardman Report confirmed that Crothers had “started to work part-time for Greensill whilst still employed in the civil service, without the required approvals.”
As Chief Commercial Officer, Crothers was responsible for the government’s commercial relationships with private suppliers — including the framework through which Greensill was operating. His simultaneous role with Greensill represented a direct, undisclosed conflict of interest at the heart of government procurement.
The Boardman Inquiry recommended improvements to the approval process for civil servants taking outside roles. ACOBA wrote a letter. No criminal investigation was launched. No financial penalty was imposed.
Sir David Manning served as Tony Blair’s chief foreign policy adviser during the period leading up to the Iraq War in 2003, and subsequently as UK Ambassador to the United States from 2003 to 2007. In these roles, he was intimately involved in the UK’s most significant defence and foreign policy decisions, including the relationship with US defence contractors and the transatlantic defence procurement framework.
After leaving the diplomatic service, Manning was appointed as a Non-Executive Director of Lockheed Martin UK. Lockheed Martin is the world’s largest defence contractor and a major supplier to the UK Ministry of Defence, holding billions of pounds in active UK defence contracts. Manning had advised on defence procurement relationships with Lockheed Martin during his time in government.
The appointment was submitted to ACOBA and approved. It was lawful and procedurally correct. The pattern it illustrates — a senior official who helped shape the UK’s relationship with a major defence contractor subsequently joining that contractor’s board — is representative of the 81% revolving door overlap rate in the defence sector.

HH cost calculation: Greensill taxpayer exposure £5.2bn (estimated across all govt-backed facilities) ÷ 28.2m households = £185; Randox contracts £540m ÷ 28.2m = £19; estimated PFI annual excess cost £2.8bn ÷ 28.2m = £100. Total: £303 per household per year.
In the parliamentary year 2020–21, approximately 330 Members of Parliament declared paid outside employment or advisory roles on the Register of Members’ Financial Interests. Total declared earnings: an estimated £5.5 million.
The debate about MPs’ second jobs is not new, but the scale documented in public records is striking. MPs receive a base salary of £86,584 (as of 2024), plus expenses, staffing allowances, and pension contributions. Despite this, approximately half of all MPs declared paid outside interests during the period reviewed — ranging from a few hundred pounds in book royalties to hundreds of thousands in legal or advisory fees.
The distribution is heavily skewed. The majority of second-job income is concentrated among a relatively small number of MPs, typically those with professional qualifications (barristers, medical consultants) or those who hold multiple advisory or non-executive roles. The top 20 earners accounted for an estimated 40% of total second-job income. Several MPs earned more from outside work than from their parliamentary salary.
| Category | Number of MPs | Estimated Total | Avg per MP | Notes |

| Legal/Barrister work | ~45 | £1.8m | £40,000 | Highest individual earners; some QCs earning £200k+ |

The argument for second jobs — that they keep MPs connected to the “real world” and bring professional expertise to Parliament — is undermined by the concentration of outside earnings in sectors with active legislative or regulatory interest. An MP serving on the Health Select Committee while receiving advisory fees from a pharmaceutical company faces a structural conflict that declaration alone does not resolve. The rules require declaration, not divestment or recusal.
Following the Paterson scandal in November 2021, the Government accepted in principle the recommendation that paid parliamentary consultancy and advisory roles should be banned. As of March 2026, the ban has not been implemented in legislation. MPs remain free to take paid advisory roles in any sector, provided they declare them on the Register.
The revolving door is not a single mechanism but a system of six interlocking layers, each reinforcing the others. Together, they create a self-sustaining architecture of private enrichment from public service.
Former ministers and senior officials are recruited as “advisers” — a role that rarely requires specific technical expertise but always requires one thing: access. Advisory fees range from £50,000 to £650,000 per year for one day per week. The value being purchased is not advice — it is the network, the knowledge of how government works from the inside, and the implicit promise of ongoing access to current officials. BlackRock, JP Morgan, and Carlyle Group have all retained former UK Chancellors or Prime Ministers in advisory roles within months of their leaving office.
Former officials retain access to their old departments through informal networks — the “quiet word in the ear” that Cameron described in 2010. Text messages, WhatsApp groups, private drinks, and personal relationships built over years in government do not end when an official leaves office. Cameron’s 56+ messages to serving ministers on behalf of Greensill demonstrate that the informal access channel is the primary mechanism through which influence is exercised — not formal lobbying registers, but personal contacts operating outside any regulatory framework.
When 81% of former MoD officials join defence companies, and 52% of former energy officials join energy firms, the regulatory boundary between public oversight and private interest dissolves. Officials who shaped the rules subsequently work for the companies those rules govern. This creates a structural incentive to design regulation that is permissive rather than restrictive — because the officials doing the designing know they will be on the other side of the boundary within a few years. The revolving door is not just a symptom of weak regulation; it is a cause of it.
Ministers are permitted to hold shares in companies operating in their policy area. Theresa Villiers held £70,000 in Shell shares while serving as Environment Secretary. The Ministerial Code requires declaration but not divestment. A minister making decisions about fossil fuel regulation while holding fossil fuel shares faces a structural conflict that no amount of declaration can resolve. The rules assume that transparency is an adequate substitute for prohibition. The evidence suggests otherwise.
Companies that employ former ministers also donate to political parties. Defence contractors, financial institutions, and energy companies appear both as employers of former officials and as major party donors. The Owen Paterson case demonstrated the loop in its most explicit form: Randox paid Paterson £100,000 per year, Paterson lobbied the FSA on Randox’s behalf, Randox received £500 million in public contracts, and the Government whipped MPs to vote against Paterson’s suspension. The interests of the company, the individual, and the party were aligned — against the public interest.
The Private Finance Initiative, championed by the Blair government, committed UK taxpayers to payments exceeding £10 billion per year for decades. Hospitals built for £200 million will ultimately cost £1.2 billion. The financial institutions that structured these deals — including JP Morgan, which subsequently employed Blair — earned hundreds of millions in advisory and arrangement fees. The PFI legacy is a lock-in: once the contracts are signed, the payments continue regardless of value for money, and the institutions that designed the structure continue to profit from its operation. The public has no exit mechanism.
The evidence documented across this report leads to a single, unavoidable conclusion: the system for managing conflicts of interest in UK public life is not broken — it was never built to work.
Eight years later, Cameron joined Greensill Capital with share options worth up to £60 million. He sent 56+ messages to serving ministers on Greensill’s behalf. When the company collapsed, the taxpayer was left exposed. No law was broken. That is the problem.
The United Kingdom has a revolving door regulator (ACOBA) with no enforcement powers, a standards system that was nearly dismantled to save one MP, a Register of Financial Interests that relies on self-declaration with no audit, and a lobbying transparency regime that covers only a fraction of lobbying activity. The result is a documented pattern of post-office enrichment that spans three decades, both major parties, and every tier of government from backbench MPs to Prime Ministers.
The total documented value of the revolving door cases examined in this report exceeds £150 million in personal enrichment for the individuals concerned. The cost to the public — through Greensill’s collapse, Randox’s VIP-lane contracts, PFI legacy payments, and the structural undermining of regulatory independence — is orders of magnitude greater.
No individual named in this report has been charged with a criminal offence in connection with the activities documented. That is not because the activities are unproblematic. It is because the law does not prohibit them.
The following reforms are drawn from the recommendations of the Committee on Standards in Public Life, Transparency International UK, and the Treasury Select Committee, supplemented by Britain Needs Us’s own analysis. None of these proposals are novel. All have been recommended by authoritative bodies. None have been implemented.
Place ACOBA on a statutory footing by Act of Parliament, with legal power to delay appointments, impose conditions, fine individuals for breaches, and refer serious cases for investigation. Give ACOBA a compliance monitoring function with dedicated staff and budget.
Extend the cooling-off period from two years to five years for Cabinet ministers and Permanent Secretaries, with mandatory ACOBA clearance before any appointment in a sector touched by the individual’s public duties. Make the cooling-off period legally enforceable.
Implement the Committee on Standards in Public Life’s 2021 recommendation to ban all paid parliamentary consultancy and advisory roles for sitting MPs. No MP should be permitted to receive payment from any company or organisation for providing advice, consultancy, or advocacy services while serving in Parliament.
Require ministers to divest all shareholdings in companies operating in their policy area within 30 days of appointment, with interests placed in a genuine blind trust. Declaration is not a substitute for divestment when the minister has decision-making power over the company’s regulatory environment.
Expand the Transparency of Lobbying Act 2014 to cover all lobbying activity — including in-house lobbyists, former ministers acting in advisory capacities, and informal approaches via personal contacts. Require a public log of all ministerial meetings, calls, and messages with private-sector representatives.
Establish an independent body — separate from the Cabinet Office — to audit the Register of Members’ Financial Interests, cross-referencing declarations with Companies House records, ACOBA approvals, and known private-sector appointments. Replace the complaints-based system with a proactive compliance regime.
Every significant reform to the UK’s conflicts of interest framework must be approved by the very Parliament whose members benefit from the current system. MPs must vote to restrict their own earning capacity. Ministers must vote to limit their own post-office opportunities. This is the fundamental structural problem: the foxes are in charge of designing the henhouse security system. Until public pressure makes the political cost of inaction greater than the personal cost of reform, the system will remain as it is — permissive, unenforceable, and profitable for those it is supposed to constrain.
