Andy Burnham is sworn in as the Labour MP for Makerfield in the House of Commons hours after Keir Starmer announces his resignation as Labour leader and prime minister. Sources report that Labour MPs cheer when Burnham enters for the swearing-in, while opposition MPs respond with good-natured jeers and teasing in the chamber. The swearing-in follows Burnham’s recent victory in the Makerfield by-election last week, where he wins the seat with more than 55% of the vote, with some reports citing a margin of around 9,000 votes. Burnham, a former Greater Manchester mayor, returns to Parliament after years away from the Commons. Several outlets also note that Burnham is expected to contend for the Labour leadership and that he publicly confirms he intends to take part in the leadership race. Reports describe Burnham meeting Labour MPs in Westminster afterwards to seek support ahead of the leadership contest. Media accounts frame the day as one of “big changes and mixed emotions” within Labour, as Starmer’s exit triggers a leadership transition and new attention on who will become the next prime minister.
