Peter Mandelson was taken into custody on suspicion of misconduct in public office following allegations that he disclosed confidential government material to Jeffrey Epstein, the convicted sex offender who died in 2019. Documents recently unsealed by the United States Department of Justice appear to indicate that, while serving as a cabinet minister, Lord Mandelson transmitted official information to Epstein. The arrest comes days after Andrew Mountbatten-Windsor, the brother of King Charles III, was detained under comparable allegations, deepening scrutiny over the reach of Epstein’s network into Britain’s political and royal circles.
