London’s Metropolitan Police on Tuesday evening opened an investigation into former U.K. ambassador to the U.S. Peter Mandelson over alleged misconduct in public office.

“Following the further release of millions of court documents in relation to Jeffrey Epstein by the United States Department of Justice, the Met received a number of reports into alleged misconduct in public office, including a referral from the U.K. government,” the Metropolitan Police said in a statement.

“I can confirm that the Metropolitan Police has now launched an investigation into a 72-year-old man, a former Government Minister, for misconduct in public office offenses,” said Police Commander Ella Marriott.

The police didn’t give a name, but 72-year-old Mandelson — a central figure in the politics of the U.K’s ruling Labour party for decades — has appeared in the latest tranche of Epstein-related documents.

Files released by the U.S. Department of Justice show emailed communications between Mandelson and Epstein, including discussions about sensitive government policy. Mandelson didn’t immediately respond to a request for comment on Tuesday evening.

A government spokesperson told POLITICO on Tuesday: “The government stands ready to provide whatever support and assistance the police need.”

Prime Minister Keir Starmer — who appointed Mandelson as the U.K.’s ambassador to the U.S. a year ago — told his Cabinet on Tuesday that the fresh allegations were “disgraceful,” according to people familiar with the meeting.
