Appointment and Early Controversy
2024 DECEMBER- MANDELSON ANNOUNCED AS WASHINGTON AMBASSADOR
Starmer picked Mandelson to be Britain's ambassador to Washington, opting for a political appointee who he said would bring "unrivalled experience" to lead relations with the U.S. under Donald Trump, newly re-elected for a second term.
He took up the post in February 2025, after he was vetted.

Starmer said he had confidence in Mandelson.

The next day, Starmer fired Mandelson as ambassador after newly released emails appeared to show that Mandelson had advised Epstein to fight for early release in 2008 when he was about to be sentenced to 18 months in jail for soliciting a minor.
The foreign ministry said the emails showed that the "depth and extent" of Mandelson's friendship with Epstein was "materially different from that known at the time of his appointment".
The following day the Independent reported that security services failed to clear Mandelson for the role, and reported that a spokesperson for Starmer said "vetting done by FCDO (the foreign ministry) in normal way."

The next day, after a speech addressing the issue, Starmer told journalists that security vetting was carried out "independently by the security services, which is an intensive exercise that gave (Mandelson) clearance for the role, and you have to go through that before you take up the post".
February 8: Resignations and Party Pressure
FEBRUARY 8 - PM'S TOP AIDE QUITS OVER MANDELSON ADVICE
Starmer's chief of staff, Morgan McSweeney, resigned, taking responsibility for advising Starmer to appoint Mandelson.
