Starmer’s Vetting Lie: The Day Due Process Became Due Deception

“Full Due Process Was Followed”: Starmer’s Despatch Box Lie Unravelled

There is a question Keir Starmer must now answer, and he cannot answer it without incriminating himself.

On 10 September 2025, the Prime Minister stood at the despatch box and told the House of Commons: “Full due process was followed during this appointment, as it is with all ambassadors.” He said it without hesitation. He has repeated variations of that statement multiple times since. His independent adviser, when the Mandelson Files were eventually dragged from Downing Street’s grip, concurred that the process had been followed. The problem, Starmer said, was that “the process wasn’t strong enough.”

That careful formulation, repeated in press conference after press conference, was designed to shift blame from a decision to a system. It was a politician’s move, not a statesman’s. And today, it has collapsed entirely.

The Guardian has revealed that Peter Mandelson failed his security vetting clearance, but that the decision was overruled by the Foreign Office to ensure he could take up his post as Ambassador to the United States. X

Read that sentence again. Mandelson did not pass vetting with reservations noted. He did not scrape through while officials held their breath. He failed. The professional assessment of the people whose job it is to make exactly this judgment was that Peter Mandelson should not be cleared for one of the most sensitive diplomatic postings in British public life. And that judgment was overruled.

This is not a process that was “not strong enough.” This is a process that was deliberately set aside…

Starmer apologised for the appointment and conceded that the rules were not good enough, but denied that he had misled the Commons, citing his independent adviser’s finding that the process had been followed. The independent adviser, it now turns out, was assessing the wrong question. The question is not whether a process existed. The question is whether it was respected. The answer, today, is no.

The vetting for one of Britain’s most sensitive diplomatic positions was conducted primarily through WhatsApp, via private accounts that do not automatically create central government records, and Starmer personally tasked Morgan McSweeney with questioning Mandelson about red flags raised during the initial civil service vetting, despite the fact that Mandelson and McSweeney were close personal friends. McSweeney’s phone, which contained those communications, has since been reported stolen.

We have covered this story from the beginning. We said, when the appointment was made, that Starmer had been warned. We said, when Mandelson was forced out, that the warnings had been ignored. We said, when the Mandelson Files were released, that the pattern of evasion pointed to something more deliberate than incompetence. Today’s revelation confirms it. The vetting system said no. Someone, somewhere in this chain of command, said yes anyway. Parliament was then told that due process had been followed.

That is a lie. It may or may not be the Prime Minister’s lie specifically. But it is his lie to own, because he made it his statement, at the despatch box, to the sovereign Parliament of this country.

The Ministerial Code is unambiguous on this point. Ministers who knowingly mislead Parliament are expected to resign. Starmer has not resigned. He has apologised for an appointment, while denying he misled anyone. Those two positions cannot both be true in light of what we now know.

The women and girls abused by Jeffrey Epstein deserved a Prime Minister who would not place their abuser’s close associate in the highest available diplomatic post. They deserved honest answers when Parliament asked how it happened. They have received neither.

The vetting system said no. A Prime Minister told Parliament yes. Parliament deserves to know which version of events Keir Starmer intends to stand by, now that only one of them remains credible.

But for now we have to ask…Who in the Foreign Office overruled the vetting decision? On whose instruction? A security clearance is not a form that bureaucrats set aside on a whim. Someone with authority made a deliberate choice to reverse a professional assessment and wave Peter Mandelson through. That person has a name. That person received an instruction, or gave one. The chain of command runs in a single direction, and at its end sits the Prime Minister’s office.

Starmer says he was lied to by Mandelson. Perhaps. But the vetting failure was not Mandelson’s lie to tell. It was a Foreign Office decision, and Foreign Offices do not override security clearances for ambassadors to Washington without political cover from somewhere above them. The question is not only what Starmer knew. The question is what he authorised, what he was told, and why, to this day, not a single official has been named, disciplined, or asked to account for the overrule.

Parliament has been misled. The public has been managed. Somewhere in the machinery of British government, a decision was taken that the security of the state mattered less than the placement of one man. We want the name of the person who made it.

There is one question this story has not yet answered, and it is the question that matters most. Who will fall on their sword for Starmer this time? Because the only thing being protected here is Starmer…
