British Police Arrest Former Ambassador Peter Mandelson in Epstein-Related Misconduct Probe
Ex-UK ambassador to Washington detained on suspicion of misconduct in public office amid disclosures from the Jeffrey Epstein document releases
British law enforcement authorities have arrested Lord Peter Mandelson, the United Kingdom’s former ambassador to the United States, as part of a criminal investigation into alleged misconduct in public office connected to his relationship with the late financier Jeffrey Epstein.
The arrest was made on Monday, February 23, 2026, when officers from London’s Metropolitan Police escorted the 72-year-old from his home in north London to a police station for interview on suspicion of misconduct in public office, reflecting allegations he shared sensitive government information with Epstein while in senior governmental roles.
The inquiry follows the release of millions of pages of files related to Epstein by the United States Department of Justice, which included communications that appear to show Mandelson passing confidential assessments of British policy and market-sensitive material to the disgraced financier.
Investigators executed search warrants at properties linked to Mandelson in the Camden and Wiltshire areas in the days leading up to his detention.
He previously resigned from the House of Lords and stepped down from the Labour Party amid the intensifying controversy, and was removed from his ambassadorial post by Prime Minister Keir Starmer in September 2025 after earlier disclosures of his Epstein ties.
Although British police do not name suspects publicly as a matter of course, images and footage of the arrest have confirmed Mandelson’s identity.
The arrest is part of a wider backlash reverberating through British politics and beyond, coming shortly after the detention of Andrew Mountbatten-Windsor, formerly Prince Andrew, on similar allegations of sharing confidential material with Epstein.
Mandelson, who has denied any wrongdoing, served in multiple senior roles including business secretary under former Labour governments and as European Union trade commissioner.
Documents released in recent weeks suggest that communications from his time in office included forwarding internal government reporting and policy deliberations to Epstein and may also reflect financial transactions between Epstein and accounts connected to Mandelson or his partner.
The unfolding investigation has amplified scrutiny of decisions by British political leadership and intensified calls for accountability in the wake of the Epstein files disclosures.
