United Kingdom Prime Minister Keir Starmer's Cabinet members have spoken out in support of him amid calls for his resignation over his former ambassador’s ties to late convicted sex offender Jeffrey Epstein.

Starmer is meeting with Labour Party members behind closed doors on Monday in an attempt to rebuild some of his weakened authority, after his office said that he does not plan to step down, The Associated Press reported.

Calls on Starmer to resign are over his appointment in 2024 of Labour politician Peter Mandelson as the U.K. ambassador to the U.S., despite his disclosed ties to Epstein. Starmer fired Mandelson in September after emails were published that revealed his friendship with Epstein.

Last month's release of the rest of the Justice Department's Epstein files showed the close relationship between Mandelson and Epstein.

On Monday, the leader of the Labour Party in Scotland, Anas Sarwar, became the most senior party lawmaker to call on Starmer to resign.
