Prime Minister Keir Starmer removed Mandelson on Sept. 11, 2025, after newly surfaced emails and a “birthday book” deepened scrutiny of his past relationship with Jeffrey Epstein; the deputy head of mission will serve in the interim.
What’s new
The dismissal followed publication of 2000s-era emails showing Mandelson offering personal support to Epstein during his legal troubles, material the government says was not known at the time of his 2025 appointment.
The “birthday book” detail
This week’s renewed focus included a 2003 “birthday book” entry in which Mandelson described Epstein as his “best pal,” intensifying political pressure in London.
Government’s explanation
A statement relayed in Parliament said the emails revealed the “depth and extent” of Mandelson’s ties were “materially different” from prior understandings, prompting his immediate withdrawal as ambassador.
Who’s in charge now
James Roscoe, the deputy head of mission in Washington, will act as interim ambassador while a permanent replacement is selected.
Political context
The firing comes amid broader scrutiny of vetting around senior appointments and ahead of high-profile U.K.–U.S. engagements, adding pressure on Starmer’s government.
