Sir Keir Starmer to step down as Prime Minister

Andy Burnham confirms he will stand to replace the outgoing Prime Minister and is backed by Wes Streeting. In a special extended World at One, Sarah Montague looks back over the legacy of Keir Starmer's time in office and ahead to what the country can expect under his likely successor. We'll hear reaction from both camps: Starmer ally and biographer Tom Baldwin, and Burnham-supporter Polly Billington MP. The BBC's Chris Mason and Henry Zeffman bring the latest analysis, as well as More in Common's Luke Tryl and the Institute for Government's Hannah White. Plus, we're joined by a member of Starmer's cabinet, Secretary of State Douglas Alexander.
