British Prime Minister Keir Starmer is facing a major crisis after revelations that his pick for U.K. ambassador to Washington, Peter Mandelson, was appointed despite failing security checks. The top Foreign Office civil servant, Olly Robbins, resigned late Thursday over the decision, but Starmer insists he will not step down. Opposition politicians have expressed disbelief that Starmer could have been unaware of the security concerns about Mandelson, whose past friendship with convicted sex offender Jeffrey Epstein was seen as a major risk.

Why it matters

The Mandelson appointment has become a major political scandal, with opposition parties calling for Starmer's resignation and accusing him of misleading the public. The revelations raise questions about the government's vetting process and Starmer's judgment in making the high-profile diplomatic appointment despite the security concerns.

The details

Documents show Starmer ignored red flags raised by his staff about Mandelson's friendship with Epstein, which exposed the government to 'reputational risk.' Mandelson was later fired in September 2025 after evidence emerged that he had lied about the extent of his links to Epstein. British police have since launched a criminal probe and searched Mandelson's homes, though he has not been charged.

  • In early 2025, the Foreign Office overruled a recommendation from security officials not to give Mandelson the ambassador role.
  • Mandelson took up the Washington post in February 2025, after undergoing security vetting.
  • Mandelson was fired in September 2025 after evidence emerged that he had lied about his links to Epstein.
  • In February 2026, British police launched a criminal probe and searched Mandelson's homes.
