Andy Burnham became Britain's prime minister on July 20, appearing outside 10 Downing Street shortly after Starmer's departure. "I go with good grace, I go with a smile," Starmer told his wife, cabinet and colleagues on Monday, ending a premiership that began with a landslide win just two years earlier.
Starmer resigned as Labour leader on June 22, having clung on after May elections in which Labour lost nearly 1,500 English council seats and power in Wales, where it fell to third with nine of 96 Senedd seats. Burnham, mayor of Greater Manchester from 2017 until his automatic disqualification in June, was blocked by Labour's NEC from contesting a February by-election but entered Parliament by winning Makerfield on June 18, after its MP resigned to make way. He was declared leader unopposed on July 17, backed by 379 of Labour's 403 lawmakers. Burnham is Britain's seventh prime minister since 2016. He inherits a sluggish economy, a cost-of-living squeeze and overstretched public services, though Labour has since drawn level with Reform UK in the polls. "I will work to build a new politics. The country is crying out for it," he said on becoming leader. The next general election is due by August 15, 2029.
