Andy Burnham Becomes UK Prime Minister — Britain's Seventh in a Decade

Andy Burnham became UK prime minister on 17 July 2026 after securing the Labour leadership with overwhelming MP support and winning the Makerfield by-election (a local vote that fills a vacant parliamentary seat). He succeeds Keir Starmer, pledging "a united Labour government free of infighting." Burnham is Britain's seventh prime minister in ten years — unprecedented in modern democratic history. Welfare, tax, and migration challenges await.
