Burnham takes office as Britain's sixth PM to arrive mid-term in a decade
Andy Burnham, the Greater Manchester mayor nicknamed 'King of the North', becomes Prime Minister on Monday and will name his cabinet the same day. He follows six leaders who left early over the past decade, from David Cameron after Brexit to Liz Truss, who lasted 49 days. Keir Starmer quit in June 2026 as Labour support drained toward Reform UK.
