British Prime Minister Keir Starmer is facing renewed political pressure after revelations that his government appointed Peter Mandelson as the United Kingdom’s ambassador to Washington despite security officials advising against the move.

Starmer said he was “absolutely furious” after learning that the Foreign Office had overridden the recommendation of security vetting officials earlier in 2025. The prime minister said he had not been informed of the decision at the time.
However, opposition politicians have questioned that claim, saying it was difficult to believe the prime minister would not have been aware of concerns surrounding the appointment.
Senior Official Resigns Over Decision
The controversy deepened after the Foreign Office’s most senior civil servant, Olly Robbins, resigned late on Thursday, taking responsibility for the decision.
Starmer said he regarded the situation as “staggering” and “unforgivable” and promised to present the full details of the case to Parliament on Monday.
Despite that pledge, the issue has become one of the most serious political challenges of his premiership. Critics say the decision to appoint Mandelson — a prominent figure in the governing Labour Party (UK) — was a major misjudgment that could ultimately threaten Starmer’s position.
Mandelson, a former European Union trade commissioner, was chosen for the Washington role partly because of his experience negotiating international trade agreements. The government hoped his background would help maintain strong economic ties with the administration of U.S. President Donald Trump.
The appointment was announced in December 2024, and Mandelson took up the post in February 2025 after undergoing security vetting procedures.
Security Concerns and Epstein Links
Security officials had warned that Mandelson’s past relationship with convicted sex offender Jeffrey Epstein posed potential reputational risks for the government.
According to the government’s chief secretary, Darren Jones, the security assessment recommended that Mandelson should not be appointed. He said the Foreign Office ultimately chose to proceed with the appointment regardless.
Jones said ministers were not informed about the outcome of the security review. He explained that the background checks, carried out by the government body known as UK Security Vetting, involve highly confidential assessments of financial, personal and other sensitive information.
Documents released earlier this year suggested that Starmer had been warned by advisers about possible reputational damage linked to Mandelson’s past association with Epstein, who died in prison in 2019 while awaiting trial on sex trafficking charges.
The controversy intensified in February after the United States Department of Justice released millions of pages of documents related to Epstein, revealing the extent of Mandelson’s contacts with the financier even after Epstein’s 2008 conviction for offences involving a minor.
Emails from 2009 appeared to show Mandelson sharing sensitive government information with Epstein while serving in the government of former prime minister Gordon Brown.
Opposition Demands Accountability
Opposition figures have strongly criticised Starmer’s explanation. Kemi Badenoch, leader of the Conservative Party (UK), said the claim that the prime minister had been unaware of the security concerns was “completely preposterous.”
“This story does not stack up,” she said, arguing that the situation pointed toward a potential resignation.
Ed Davey, leader of the Liberal Democrats (UK), said Starmer would have to step down if it emerged that he had misled Parliament or the public about the appointment.
Starmer dismissed those claims but acknowledged that trusting Mandelson had been a serious mistake. The prime minister dismissed Mandelson in September 2025 after evidence emerged that he had misrepresented the extent of his links with Epstein.
Starmer has since apologised to the public and to Epstein’s victims for what he described as believing “Mandelson’s lies.”
Criminal Investigation Continues
British police later launched a criminal investigation into Mandelson’s conduct and searched properties linked to him in London and western England.
Mandelson was arrested in February on suspicion of misconduct in public office. He has denied wrongdoing and has not been formally charged. Authorities say the investigation remains ongoing.
Separately, Andrew Mountbatten-Windsor, the brother of Charles III, is also under investigation over his own links to Epstein. He has likewise been arrested but has not been charged.
The developments have placed additional pressure on Starmer as he prepares to address Parliament about the controversy.
