Senior British official resigns over Mandelson appointment, but Starmer insists he won't go

LONDON (AP) — British Prime Minister Keir Starmer has no plans to resign over revelations that his scandal-tainted pick for U.K. ambassador to Washington was appointed despite failing security checks, officials said Friday.

Starmer says he was unaware that the Foreign Office had overruled the recommendation of security officials in early 2025 not to give Peter Mandelson the job. Many considered Mandelson a risky appointment because of his past friendship with convicted sex offender Jeffrey Epstein.

The top Foreign Office civil servant, Olly Robbins, took the fall for the decision and resigned late Thursday. Starmer is due to make a statement to Parliament on the issue on Monday.

That’s unlikely to end the danger to the prime minister over his fateful decision to appoint Mandelson, a trade expert and elder statesman of the governing Labour Party, as envoy to the Trump administration. It was a calculated risk that backfired spectacularly, and could bring down the prime minister.

Opposition politicians expressed disbelief that Starmer could have been unaware Mandelson had failed security vetting. Starmer’s office said he only found out this week.

Darren Jones, the chief secretary to the prime minister, said Friday that “the recommendation was to not appoint Peter Mandelson to the role,” and that the Foreign Office ignored it. He said that was “astonishing,” but within the rules.

He said no government minister had been told of the security assessment.

Opposition Conservative Party leader Kemi Badenoch said claims the prime minister didn’t know were “completely preposterous.”

“This story does not stack up. The prime minister is taking us for fools,” she told the BBC. “All roads lead to a resignation.”

Ed Davey, the leader of the centrist Liberal Democrats, said Starmer “must go” if he misled Parliament and lied to the British public.

Starmer has repeatedly insisted that “due process” was followed in the appointment, which was announced in December 2024. Mandelson took up the Washington post in February 2025, after undergoing security vetting.

But documents released by the government in March, after being forced to by Parliament, showed Starmer ignored red flags raised by his staff. He was warned that Mandelson’s friendship with Epstein, who died in prison in 2019, exposed the government to “reputational risk.”

Starmer fired Mandelson in September 2025 after evidence emerged that he had lied about the extent of his links to Epstein.

Starmer’s premiership faced its biggest crisis in February after the release of millions of pages of Epstein-related documents by the U.S. Department of Justice showed the closeness of Mandelson’s relationship with the financier, even after Epstein’s conviction in 2008 for sexual offenses involving a minor.

Emails between the men suggested Mandelson had passed on sensitive — and potentially market-moving — government information to the disgraced financier in 2009, when he was a member of Prime Minister Gordon Brown’s government.

British police subsequently launched a criminal probe and searched Mandelson’s two houses in London and western England. Mandelson was arrested on Feb. 23 on suspicion of misconduct in public office.

He has been released without bail conditions as the police investigation continues. Mandelson has previously denied wrongdoing and hasn’t been charged. He does not face allegations of sexual misconduct.

Starmer has apologized to the British public and to Epstein’s victims for believing what he has termed “Mandelson’s lies.”
