Andy Burnham, leader of the Labour Party, officially took office as Prime Minister of the United Kingdom on Monday, 20 July, after an audience with King Charles III at Buckingham Palace, pledging to bring the biggest change in 40 years to a new politics and economy. Burnham announced his new cabinet on the same day, with John Healey as Chancellor of the Exchequer, Ed Miliband as Foreign Secretary, Shabana Mahmood continuing as Home Secretary, Lewis Hague as First Deputy Prime Minister and Minister for the Duchy of Lancaster and Minister for the Cabinet Office, Yvette Cooper as Health Secretary, Pat McFadden continuing as Work and Pensions Secretary, Angela Rayner as Housing, Communities and Local Government Secretary, Jonathan Reynolds as Business, Innovation, Science and Trade Secretary, and Wes Streeting as Defence Secretary. This cabinet faces challenges of a sluggish economy, inadequate public services, high living costs, and a fractured political landscape. Burnham will announce cost-of-living support measures on 21 July and a 10-year long-term plan for the UK later this year.
