Andy Burnham has won a thumping victory in Makerfield, proving he can, in certain circumstances, beat Nigel Farage’s Reform UK – but what about beating his own party leader Sir Keir Starmer?

The prime minister says he will stand and fight any leadership challenge. So, where does it leave the country? Will Starmer be forced to stand down, despite his defiant tone now? And what will happen if there is a leadership election?

On this episode of The Fourcast Krishnan Guru-Murthy is joined by Keir Starmer’s biographer Tom Baldwin, Labour MP and Wes Streeting ally Rosie Wrighting, Labour MP and Andy Burnham supporter Dr SImon Opher and More In Common executive director Luke Tryl.
