Is Keir Starmer set to resign as Labour's Andy Burnham lines up a challenge backed by 200 MPs?

Pressure is mounting on UK Prime Minister Keir Starmer as internal Labour tensions intensify following poor local election results and growing speculation about a possible leadership challenge. Reports suggest that as many as 200 Labour MPs could support Greater Manchester Mayor Andy Burnham in a potential bid to replace Starmer, amid claims of a widening split within the party. Starmer has rejected calls to resign, insisting he will contest any leadership challenge and warning that a contest could destabilize both the party and government. The situation reflects growing uncertainty within Labour as economic pressures and falling approval ratings continue to fuel political debate.
