UK Prime Minister Keir Starmer is facing calls to resign after it was revealed that disgraced former British Ambassador to the US Peter Mandelson had been appointed despite not being cleared by security officials. Mandelson, who served as London's envoy in Washington in 2025, was arrested earlier this year over allegations that he leaked sensitive government data to convicted sex trafficker Jeffrey Epstein, with whom he maintained friendly relations even after Epstein's imprisonment in 2008.

Why it matters

The revelation that Starmer misled Parliament about the appointment of an Epstein-linked diplomat has dealt a major blow to the Prime Minister's credibility and authority, fueling calls for his resignation from opposition parties and the media.

The details

The Guardian reported that Mandelson had failed the vetting process by the Cabinet Office in 2024, but the Foreign Office ignored the recommendation and still made him ambassador. Downing Street confirmed the report, but claimed Starmer was unaware of Mandelson's security clearance problems when he previously assured Parliament that 'due process' had been followed.

  • Mandelson served as British Ambassador to the US from February to September 2025.
  • Mandelson was arrested earlier this year over allegations that he leaked sensitive government data to Jeffrey Epstein.
  • The Cabinet Office reportedly rejected Mandelson's security clearance in 2024, but the Foreign Office still appointed him as ambassador.
