In 2019, UK's
Channel 4 aired an episode of
Dispatches in which a source close to sex offender
Jeffrey Epstein said that Mandelson (while serving as a UK Cabinet Minister) made a phone call to Epstein in order to set up a meeting with
Jamie Dimon, CEO of
JPMorgan. In June 2023, an internal JPMorgan report from 2019, filed to a New York court, found that "Jeffrey Epstein appears to maintain a particularly close relationship with
Prince Andrew, Duke of York, and [Peter] Lord Mandelson, a senior member of the British Government."

In February 2025, when asked about his relationship with Epstein by the
Financial Times, Mandelson said: "I regret ever meeting him or being introduced to him by his partner
Ghislaine Maxwell. I regret even more the hurt he caused to many young women. I'm not going to go into this. It's an FT obsession and frankly you can all fuck off. OK?"
[142][17]
On 9 September 2025, the
U.S. House Oversight Committee published a series of documents from Epstein's estate, which included a letter written by Mandelson to Epstein in 2003.
[143][144][145] The letter was part of a '
birthday book' compiled by Maxwell, for Epstein's 50th birthday in 2003.
[143] Within that letter, Mandelson described Epstein as an "intelligent sharp-witted man" and as "my best pal".
[144] A number of pictures of Mandelson, including one with Epstein, were published alongside the letter.

On 10 September 2025, further communication from Mandelson to Epstein was published widely, including an email sent in June 2008 after Epstein's conviction for soliciting prostitution from someone aged under 18 and before his sentencing, where he wrote: "You have to be incredibly resilient, fight for early release and be philosophical about it as much as you can. The whole thing has been years of torture and now you have to show the world how big a person you are, and how strong. I think the world of you and I feel hopeless and furious about what has happened. I can still barely understand it. It just could not happen in Britain. Everything can be turned into an opportunity and that you will come through it and be stronger for it. Your friends stay with you and love you".
[146][147] In a response to the email, Mandelson said: "I relied on assurances of his innocence that turned out later to be horrendously false."
[146]
The published communications led to Mandelson facing repeated calls to resign as Britain's ambassador to the US, including from multiple Labour MPs and the
Leader of the Opposition,
Kemi Badenoch, though Starmer expressed confidence in him on 10 September 2025 at
Prime Minister's Questions, stating "Let me start by saying that the victims of Epstein are at the forefront of our minds. He was a despicable criminal who committed the most heinous crimes and destroyed the lives of so many women and girls. The ambassador has repeatedly expressed his deep regret for his association with Epstein, and he is right to do so. I have confidence in him, and he is playing an important role in
the UK-US relationship."
[148][18]
Mandelson was sacked by Starmer on 11 September 2025 following the publication in
The Sun newspaper of supportive emails Mandelson sent to Epstein after he was arrested in 2008.
[149] Foreign Office minister
Stephen Doughty said these emails showed "the depth and extent of Peter Mandelson's relationship with Jeffrey Epstein is materially different from that known at the time of his appointment. In light of that, and mindful of the victims of Epstein's appalling crimes, he has been withdrawn as ambassador with immediate effect."
