British Prime Minister Keir Starmer fought to save his job Monday as he tried to persuade Labour Party lawmakers not to oust him after just a year and a half in office.

Starmer’s head of communications, Tim Allan, said he was quitting Monday to allow "a new No. 10 team to be built." The prime minister lost his chief of staff Sunday and is rapidly shedding support from Labour legislators after revelations about the relationship between former British Ambassador to Washington Peter Mandelson and the late sex offender Jeffrey Epstein.

Starmer is due to address Labour lawmakers behind closed doors later Monday in an attempt to rebuild some of his shattered authority.

The political storm stems from Starmer's decision in 2024 to appoint Mandelson to Britain’s most important diplomatic post, despite knowing he had ties to Epstein.

Starmer fired Mandelson in September after emails were published showing that he maintained a friendship with Epstein after the financier’s 2008 conviction for sex offenses involving a minor.
