Peter Mandelson
British politician / Former UK Ambassador to the USA · British · Under criminal investigation (misconduct in public office) — resigned Labour Party and House of Lord
Peter Benjamin Mandelson, Baron Mandelson (born October 21, 1953) is one of the most significant figures in British Labour Party politics, having served as a senior minister and strategist under both Tony Blair and Gordon Brown. He served twice in Blair's cabinet before resigning over personal financial controversies, and served as EU Trade Commissioner from 2004 to 2008. In 2025, Prime Minister Keir Starmer appointed him as UK Ambassador to the United States -- one of the most senior diplomatic postings in British government.
Mandelson's connection to Epstein has been documented across multiple source types. A 2023 internal JPMorgan report filed in New York court described Epstein as maintaining "a particularly close relationship" with both Prince Andrew and Mandelson. It appears Mandelson was introduced to Epstein through Ghislaine Maxwell. Emails released in the 2025 DOJ document releases showed Mandelson and Epstein in correspondence until at least 2016, discussing Donald Trump's entry to the White House and Mandelson's personal life.
In September 2025, emails emerged showing that in 2009 -- shortly before Epstein's sentencing -- Mandelson had written to urge Epstein to "fight for early release." The revelation led to his immediate dismissal as UK Ambassador by Prime Minister Starmer. The emails also suggested Mandelson may have shared sensitive UK government information with Epstein while a member of Gordon Brown's cabinet, a potentially serious breach of official secrecy.
In February 2026, following the broader DOJ document releases, Mandelson was arrested and released on bail as part of wider law enforcement activity relating to Epstein's network. He has denied wrongdoing and is contesting the allegations. The arrest of a former senior UK government minister and EU commissioner represents one of the most significant developments in the ongoing Epstein accountability proceedings.
On February 1, 2026, following the DOJ's January 30 document release, Mandelson resigned his Labour Party membership to avoid causing the party "further embarrassment." He resigned from the House of Lords on February 3, 2026, effective the following day — the same day the Metropolitan Police announced a formal criminal investigation into him for suspected misconduct in public office. Police subsequently searched two properties linked to Mandelson. Downing Street Chief of Staff Morgan McSweeney also resigned, saying he took "full responsibility" for having recommended Mandelson's ambassadorial appointment despite knowing of his Epstein ties.
