UK Files Reveal Starmer’s Controversial Appointment of Peter Mandelson as US Ambassador

Starmer appointed Mandelson despite warned reputational risk – Prime Minister Keir Starmer was cautioned that Mandelson’s friendship with convicted sex offender Jeffrey Epstein posed a reputational danger, yet he still named Mandelson UK ambassador to the United States, according to documents released on Wednesday [1].

Mandelson dismissed after nine months when new Epstein details emerged – Starmer removed Mandelson from the post in September after further evidence of his ongoing contact with Epstein surfaced, ending a nine‑month tenure [4].

Due‑diligence report documented a decade‑long Epstein connection – A senior civil‑service “due diligence” memo from December 2024 traced Mandelson’s ties to Epstein from at least 2002, noting he facilitated a 2002 meeting with then‑PM Tony Blair, stayed at Epstein’s house in June 2009, and was highlighted in a 2019 JPMorgan report linking him closely to Prince Andrew [1].

Cabinet minister Darren Jones said the report missed the friendship’s depth – Jones told the Commons that the due‑diligence review failed to expose the full extent of Mandelson’s relationship, that Mandelson lied to Starmer, and called the appointment a mistake [1].

Mandelson arrested on suspicion of misconduct, no charges filed – Police detained the 72‑year‑old at his London home on Feb. 23 on suspicion of misconduct in public office; he was released without bail, has denied wrongdoing and has not been charged [9].

Political fallout includes calls for Starmer’s resignation and a fragile premiership – The release of a massive DOJ file trove in January spurred opposition and some Labour members to demand Starmer step down, though he survived the immediate crisis, his leadership remains under pressure [6][7].
