We look at two Labour leadership hopefuls setting out their visions for the UK ahead of a Labour leadership contest that hasn’t even begun. Greater Manchester Mayor Andy Burnham told the BBC he’d 'save' Labour, and Wes Streeting has confirmed that he would run in the event of a formal challenge to Keir Starmer. Before Burnham can run for leader, and therefore PM, he’s got to win the Makerfield by-election first. Laura and Paddy answer Newscasters’ questions on the subject and look at a potential cautionary tale from a by-election in 1965. You can now listen to Newscast on a smart speaker.
