The Revolving Door Spins Again
Another week, another senior mandarin announces a departure from Whitehall — and, in due course, another lucrative appointment materialises at a firm that spent years lobbying the department they just left. The pattern is so well established that it barely registers as news any more. It should. The movement of senior government officials directly into private sector roles with companies they previously regulated, advised, or awarded contracts to is not merely an ethical curiosity. It is a structural corruption at the heart of British public life, and the body charged with preventing it has proved, repeatedly, that it is neither willing nor equipped to do so.
The Advisory Committee on Business Appointments — ACOBA — is the watchdog responsible for scrutinising the post-employment plans of ministers, senior civil servants, and military officers. It sounds reassuring. It is anything but. ACOBA has no statutory power to block appointments. It can impose waiting periods and recommend conditions. It cannot enforce them. When its guidance is ignored, as it routinely is, it can write a stern letter. That is the full extent of its arsenal. For a body nominally tasked with safeguarding public trust in government, it is extraordinarily well designed to fail.

What the Numbers Tell Us
The scale of the problem is not trivial. Transparency International UK has documented hundreds of cases in which senior officials moved into roles with direct commercial relevance to their former positions. Defence procurement officials joining defence contractors. Treasury officials moving to asset management firms. NHS executives taking directorships at healthcare technology suppliers. The waiting periods ACOBA recommends — typically between one and two years — are often insufficient to neutralise the value of inside knowledge, personal relationships, and regulatory familiarity that these individuals carry with them.
A 2022 report by the Institute for Government found that compliance with ACOBA's conditions was inconsistent and that the committee itself lacked the resources to conduct meaningful follow-up. The government's own transparency data, published intermittently and often with considerable delay, reveals a steady stream of approvals granted with minimal scrutiny. In many cases, applicants are simply told to avoid drawing on specific privileged information — a condition that is functionally unverifiable once someone is sitting in a private boardroom.
This Is Not the Free Market. It Is a Corruption of It.
The standard defence of these appointments is that they represent the natural operation of a competitive labour market. Talented people, the argument runs, should be free to take their skills wherever they are valued. This is a reasonable principle applied to an entirely unreasonable set of circumstances. The civil servant who spent a decade overseeing defence procurement was not building marketable expertise in a vacuum. They were doing so on a salary funded by the public, with access to commercially sensitive information that no private sector rival could obtain, and with the power to shape the very regulatory environment that determines winners and losers in their sector. To then monetise that access in the private sector is not the free market at work — it is the exploitation of a publicly funded advantage for personal gain.
Conservatives, of all people, should be the first to call this out. The case for free markets rests on the assumption that competition is genuine, that no participant enjoys an unfair advantage derived from proximity to state power. The revolving door corrodes that assumption entirely. It creates a class of insiders whose value to private employers lies not in their talent but in their contacts — and those contacts were cultivated at public expense. This is cronyism, and it discredits the very enterprise culture that conservatives are right to champion.
The Strongest Counter-Argument, and Why It Falls Short
Some will argue that restricting post-employment options for civil servants would deter talented individuals from entering public service in the first place. If Whitehall cannot compete on salary, the argument goes, it must at least offer the prospect of a lucrative exit. There is something to this — public sector pay at senior levels is genuinely uncompetitive, and the recruitment challenges are real. But this argument proves too much. It essentially concedes that the current system functions as a deferred compensation arrangement, in which the private sector underwrites public service careers in exchange for preferential access later. That is not a defence of the status quo. It is a description of exactly what is wrong with it.
The solution is not to make the revolving door spin faster. It is to pay senior officials properly, impose genuinely enforceable restrictions on post-employment activity, and give ACOBA the statutory teeth it currently lacks — including the power to block appointments outright and impose financial penalties for non-compliance.
Reform That Is Long Overdue
The Conservative Party spent years in government with the opportunity to reform ACOBA and declined to do so with any seriousness. Labour, now in office, has shown no greater appetite for change. Neither party has a strong incentive to dismantle a system from which their own former ministers and officials frequently benefit. That, in itself, tells you something important about where the political will — or the lack of it — actually lies.
The public, for their part, are not naive. Poll after poll shows that trust in politicians and public institutions has collapsed over recent decades, and the perception that government exists to serve a well-connected elite rather than ordinary citizens is a significant driver of that collapse. The revolving door is not the only cause, but it is one of the most visible symptoms — and visibility matters in politics.
Any serious programme of constitutional conservatism — one committed to accountable institutions, genuine meritocracy, and the integrity of public life — must put ACOBA reform at its centre. Statutory blocking powers. Extended cooling-off periods for the most sensitive roles. Mandatory public disclosure with real-time transparency. And, crucially, a culture shift within Whitehall that treats the exploitation of public office for private gain as the scandal it is, rather than the career milestone it has quietly become.
The revolving door will keep spinning until someone has the courage to shut it — and the electorate should demand to know why, after so many years, nobody in power has bothered to try.
