LONDON (AP) — On Sunday, senior Cabinet ministers expressed their support for U.K. Prime Minister Keir Starmer, whose political stability is being challenged by his controversial decision to appoint former Labour politician Peter Mandelson as Britain’s ambassador to the United States. Mandelson’s association with Jeffrey Epstein and previous scandals have intensified scrutiny and backlash, particularly following revelations that he failed security checks necessary for the highly significant diplomatic role.
Starmer is anticipated to face a tense session in Parliament on Monday, where he will need to defend his leadership after it was disclosed that Mandelson was appointed despite intelligence indicating that he should not have been granted security clearance. Starmer expressed his anger at not being informed during the vetting process in January 2025, as the Foreign Office, responsible for diplomatic appointments, approved Mandelson’s appointment regardless of the prior warnings.
Deputy Prime Minister David Lammy stated that if Starmer had been aware of the security concerns, he "would never, ever have appointed him ambassador." Technology Secretary Liz Kendall echoed this sentiment in an interview, emphasizing Starmer's integrity and suggesting that he would not have moved forward with the appointment had he known of the security issues.
The crisis escalated when Olly Robbins, the highest-ranking civil servant in the Foreign Office, submitted his resignation on Thursday. Allies of Robbins claim he is unjustly being made a scapegoat, as he was merely executing his responsibilities. Robbins is set to provide his account to the House of Commons Foreign Affairs Committee on Tuesday, a move anticipated to shed more light on the controversial appointment process.
Former Foreign Office civil servant Simon McDonald criticized the situation, stating that Robbins was "thrown under the bus." McDonald indicated that the vetting information would be considered highly sensitive and traditionally kept from the prime minister and his team.
The political fallout has led all major opposition parties to call for Starmer’s resignation. Specifically, Conservative Party leader Kemi Badenoch described Starmer’s position as "untenable," while Ed Davey, leader of the Liberal Democrats, referred to the government as being "in perpetual crisis," arguing that Starmer must resign for any resolution to occur. Despite strong opposition, Starmer’s Labour Party commands a considerable majority in the Parliament, meaning the real threat to his leadership comes from his own party members, many of whom are already concerned about the party’s poor polling performance.
Starmer previously navigated a potential leadership challenge in February, when calls for his resignation arose again due to the Mandelson appointment. However, political analysts suggest he could still be vulnerable to a leadership challenge following local and regional elections on May 7, where Labour is predicted to perform poorly. While some Labour lawmakers argue that a leadership change amidst global instability could be detrimental, others are disheartened by Starmer's repeated mistakes and failure to revive the party’s fortunes since his election victory in July 2024.
Critics frequently highlight Mandelson's appointment as evidence of Starmer’s poor judgment. Documents released in March revealed that Starmer was warned about potential reputational risks associated with Mandelson’s ties to Epstein, who died in prison in 2019 after being convicted for sexual offenses involving a minor. Despite these concerns, Starmer believed Mandelson's expertise as a former EU trade chief and his connections with global elites would benefit relations with President Donald Trump’s administration.
Mandelson ultimately served less than nine months in his ambassadorial role. After evidence surfaced of his dishonesty regarding his links to Epstein, Starmer terminated his appointment in September 2025. Following the release of extensive Epstein-related documents by the U.S. Department of Justice in January, new details emerged highlighting Mandelson’s continued association with Epstein, even post-conviction, as well as indications that he may have shared sensitive governmental information with Epstein.
In light of the developments, British police launched a criminal investigation into Mandelson. He was arrested on February 23, 2026, on allegations of misconduct in public office, although he has since been released without conditions as the inquiry is ongoing and has denied any wrongdoing. Notably, Mandelson does not face any accusations of sexual misconduct.
