Mandelson Failed Vetting, the FCDO Overruled It in 48 Hours — Starmer Says He Didn’t Know, Sacks a Permanent Secretary, Apologises, and Faces Opposition Calls to Resign as the Epstein Papers Reopen at the Worst Possible Moment

What the Guardian reported

Developed vetting is the deepest level of UK national security clearance, required for access to strategic defence and intelligence material at the heart of the Anglo-American alliance. The Washington ambassador, by definition, needs it. Mandelson applied in early January 2025. UK Security Vetting completed the process in the standard window and returned a decision: fail. The documented reason centred on his acknowledged historical relationship with Jeffrey Epstein, the existence of correspondence with Epstein the vetting panel assessed as a live counter-intelligence vulnerability, and a pattern of non-disclosure during the interview stage.

Within 48 hours of that decision, the FCDO invoked a rare authority under Cabinet Office vetting procedure that permits the appointing department to override a vetting outcome if the minister responsible judges that override to be in the public interest. The override was signed by the permanent secretary. The then-Foreign Secretary approved the submission. The document submission did not appear on Starmer’s desk.

What Starmer has done in the last 36 hours

The PM was told on Wednesday afternoon, eight hours before the Guardian filed. Downing Street’s first response on the record — issued at 7:42pm — said the Prime Minister had been unaware of the vetting override until this month. Number 10 confirmed he accepted that, as premier, the buck stopped with him; he apologised for the appointment; he accepted Mandelson’s sacking as ambassador, which had already happened in February over the Epstein Congressional disclosures; and he committed to publishing every document in the FCDO paper trail by Monday.

The permanent secretary who signed the override has been asked to leave post by the end of the week. Starmer ordered that personally. It is the first Whitehall sacking at permanent-secretary level this parliament. The outgoing civil servant has not yet commented. FCDO colleagues are furious — there is a view inside King Charles Street that the override was done in the knowledge and with the approval of the political class, and a single civil servant is being thrown overboard to insulate them.

The Epstein timebomb

This is the second Mandelson-Epstein eruption of the parliament. The first came in February, when a US House Oversight Committee release included correspondence suggesting Mandelson’s contact with Epstein continued years later than Mandelson had publicly admitted and included exchanges touching on live government business in 2008. Starmer sacked him as ambassador within 72 hours of that release. The Metropolitan Police arrested and bailed Mandelson ten days later on suspicion of misconduct in public office. That investigation is ongoing.

The new problem is not what Mandelson did. The new problem is what Whitehall knew when it put him in Washington anyway. The vetting override document exists. It names the officials who signed it. It was written within 48 hours of a formal risk assessment that concluded exactly what the House Oversight Committee would later confirm. Either the people who signed the override knew the Epstein exposure and did it anyway, or they did not read the vetting file properly. Neither explanation survives disclosure.

The Opposition move

Badenoch has tabled an Urgent Question for Monday and written to the Cabinet Secretary demanding a full investigation. Ed Davey called it “a scandal of judgement at the very top.” Nigel Farage put out a Truth Social-style post calling it “proof Labour cannot be trusted with national security.” The Lords will almost certainly demand a statement from the Foreign Secretary on Tuesday. Starmer’s own backbench has split: 38 MPs signed a letter demanding “full transparency,” a phrase that is the Westminster equivalent of loading a shotgun.

The arithmetic of Labour patience now turns on the release. If the FCDO paper trail shows no evidence that Starmer was informed before February, he survives — battered, wounded, but survives. If anything in it puts a submission in front of him that he signed or initialled in early 2025, the premiership ends. MPs who spent Wednesday night messaging the Whips Office say they have rarely seen the building more pessimistic. The local elections are 20 days away.
