Former British ambassador to Washington, Peter Mandelson, has been asked to cooperate with a United States congressional investigation into late convicted sex offender Jeffrey Epstein.
In a letter sent by Democratic Representatives, Robert Garcia and Suhas Subramanyam, members of the US House Oversight Committee, the lawmakers requested that Mandelson make himself available for a transcribed interview.
The committee stated that it believes Mandelson possessed extensive social and business ties to Epstein and may hold critical information relevant to its ongoing investigation into the financier’s network and alleged accomplices.
Although the committee does not have the legal authority to compel Mandelson to testify, it said it was seeking his voluntary cooperation and expects a response on or before February 27, 2026.
Mandelson served as the United Kingdom’s ambassador to the United States from February 2025 before his removal in September amid growing controversy over his association with Epstein. He has since stepped down from the House of Lords and resigned from the Labour Party.
The development has intensified political pressure on UK Prime Minister, Keir Starmer, with critics questioning his decision to appoint Mandelson to what is considered Britain’s most prestigious diplomatic post.
In recent days, the controversy has reportedly led to the resignation of several senior aides within Starmer’s government, further deepening the political fallout.
Mandelson has consistently denied any criminal wrongdoing in connection with his relationship with Epstein.
