Former UK Home Secretary says Keir Starmer's resignation was 'inevitable' | 7.30

British Prime Minister Sir Keir Starmer has announced his resignation. The resignation was triggered by the runaway success in a weekend by-election of his chief challenger and likely successor, the so-called 'King of the North' Andy Burnham, who is now headed to Westminster to be sworn in as MP for Makerfield, giving colleagues hope that Labour can still defeat the surging populist Reform Party at the next election. Burnham was an MP from 2001 to 2017 and then became Mayor of Manchester. If successful in his bid to become the next Prime Minister, he will become Britain's seventh leader in a decade. Alan Johnson was the UK Home Secretary under Gordon Brown and a long-time supporter of Sir Keir Starmer. He spoke to 7.30's Sarah Ferguson.
