UK’s Former Ambassador to Washington Faces Investigation and Quits Parliament Amid Epstein Ties
Peter Mandelson steps down from the House of Lords as British authorities launch a criminal inquiry into his links with Jeffrey Epstein and the alleged sharing of sensitive government information
The United Kingdom’s former ambassador to the United States, Lord Peter Mandelson, has become the subject of a criminal investigation and announced his imminent resignation from the House of Lords as new disclosures about his relationship with late convicted sex offender Jeffrey Epstein continue to unfold.
British police have confirmed that detectives will investigate potential misconduct in public office related to reports that Mandelson shared confidential government information with Epstein, reaching the threshold for a formal probe by the Metropolitan Police.
This development has intensified scrutiny of Mandelson’s conduct during his time in government and abroad.
Mandelson, a veteran Labour politician who served in senior ministerial roles for decades before becoming ambassador to Washington, resigned from the Labour Party in February, saying he did not wish to cause further embarrassment amid renewed attention to his ties to Epstein after the release of U.S. Department of Justice documents.
The former ambassador was dismissed from his diplomatic post in September 2025 after earlier revelations about his association with Epstein, including correspondence and alleged financial transfers.
Mandelson denies recalling the transfers and has questioned the authenticity of some documents.
Prime Minister Keir Starmer has publicly said that Mandelson “let his country down” and urged reforms to allow the removal of peers who bring the House of Lords into disrepute.
Starmer ordered an urgent internal review of Mandelson’s contacts with Epstein during his time as a government minister and has called for modernising disciplinary procedures to strip him of his title.
As part of the expanding backlash, the scandal has raised broader questions about vetting processes for key diplomatic appointments and the extent of influence wielded by Epstein within elite political circles.
Mandelson is expected to formally retire from the House of Lords on February 4, bringing to a close his long and once-distinguished political career amid one of the most striking reputational crises of recent British public life.
