Wiktor Szymanowicz | Future Publishing | Getty ImagesHello, this is Leonie Kidd coming to you from London. New day, new faces in the British government. And the freshly appointed Ministers to the top spots of the U.K. cabinet will be of interest to those both inside and outside the country...What you need to know todayIt's all change at Downing Street. Britain's new Prime Minister Andy Burnham has marked his first day in government with a surprise appointment to the role of Chancellor of the Exchequer. John Healey has been named as finance minister in a move that has caught commentators and markets off guard, as his name was absent from speculation before the appointment. Healey was Defense Minister under the previous government under now-former Prime Minister, Keir Starmer. He was one of the first to resign from his role, following a row over defense spending, helping to trigger the leadership challenge. Healey was a minister in the Treasury under then-Chancellor Gordon Brown back in the early 2000s.His appointment is an interesting development for Britain's contentious defense budget. Healey has been consistent in his call for the government to set a date to spend 3 percent of GDP on defense. Other key appointments include Ed Miliband in the role of Foreign Secretary and Wes Streeting as Defense Secretary, while Shabana Mahmood — who had been tipped to be named Chancellor — will stay at the Home Office.
