Keir Starmer is fighting to regain control over the Labour Party following the resignation of his top adviser, Morgan McSweeney. McSweeney stepped down and took "full responsibility" for recommending Peter Mandelson as the next UK ambassador to the United States. That choice sparked widespread fury because of Mandelson’s past ties to Jeffrey Epstein.

While Starmer’s internal circle hopes this move will calm angry MPs, losing such a close aide is a massive setback that leaves the Prime Minister vulnerable. The spotlight is now shifting back to Starmer’s personal role in the appointment. Tensions are expected to rise further as more documents about the decision are released to the public.
