Former British Ambassador to Washington Peter Mandelson has been asked to appear in person for an interview and answer questions as part of the US Congress’ investigation into convicted sex offender Jeffrey Epstein.
In a letter sent to Mandelson by Democratic Reps. Robert Garcia and Suhas Subramanyam on the House Oversight Committee, the lawmakers said it was “clear” that the former ambassador had “extensive social and business ties” to Epstein and asked him to provide a transcript of the interview.

“The committee aims to uncover the identities of Mr. Epstein’s co-conspirators and perpetrators and to understand the full scope of his criminal activities,” the lawmakers said in the letter.
“Although you are no longer the British Ambassador to the United States and have resigned from the House of Lords, it is clear that you have extensive social and business connections with Jeffrey Epstein and hold important information regarding our investigation into his activities,” they said.
“Massive evidence has come to light showing your close relationship with Jeffrey Epstein over several years,” they added.
The House of Commons committee does not have the power to compel Mandelson to testify, but said it was asking for his “cooperation” and expected a response “no later than February 27, 2026.”
Mr Mandelson became British ambassador in February 2025 but was sacked in September after Prime Minister Keir Starmer’s government claimed further details had emerged about the depth of his relationship with Mr Epstein.
He later resigned from Starmer’s Labor Party following increased scrutiny from the House of Lords.
Mandelson’s ties to Epstein have led to calls for Starmer to step down as prime minister, and critics have questioned his decision to appoint Mandelson as US ambassador, considered the most prestigious post in British diplomacy.

Mr Starmer appears to be surviving for now, but the controversy continues to resonate within his inner circle.
Chris Wormald, Prime Minister Starmer’s cabinet secretary, resigned on Thursday. He is the third senior prime minister’s aide to resign within days over the Epstein scandal.
Mr Starmer’s chief of staff, Labor stalwart Morgan McSweeney, resigned on Sunday to advise him on Mr Mandelson’s controversial appointment, as did communications director Tim Allan.
Mr. Mandelson denies any criminal wrongdoing in connection with his relationship with Mr. Epstein.
