Tony Blair resigns as British Prime Minister, a position he had held since 1997. Chancellor Gordon Brown succeeds him.

Sir Anthony Charles Lynton Blair is a British politician who served as Prime Minister of the United Kingdom from 1997 to 2007 and Leader of the Labour Party from 1994 to 2007. He was Leader of the Opposition from 1994 to 1997 and held various shadow cabinet posts from 1987 to 1994. Blair was Member of Parliament (MP) for Sedgefield from 1983 to 2007, and was special envoy of the Quartet on the Middle East from 2007 to 2015. He is the second-longest-serving prime minister in post-war British history after Margaret Thatcher, the longest-serving Labour politician to have held the office, and the first and only person to date to lead the party to three consecutive general election victories. Blair founded the Tony Blair Institute for Global Change in 2016, and currently serves as its Executive Chairman.

The prime minister of the United Kingdom is the head of government of the United Kingdom. The prime minister advises the sovereign on the exercise of much of the royal prerogative, chairs the Cabinet, and selects its ministers. Modern prime ministers hold office by virtue of their ability to command the confidence of the House of Commons, so they are invariably members of Parliament.

The chancellor of the exchequer, often abbreviated to chancellor, is a senior minister of the Crown within the Government of the United Kingdom, and the head of His Majesty's Treasury. As one of the four Great Offices of State, the chancellor is a high-ranking member of the British Cabinet.

James Gordon Brown is a British politician who served as Prime Minister of the United Kingdom and Leader of the Labour Party from 2007 to 2010. Previously, he was Chancellor of the Exchequer from 1997 to 2007 under Tony Blair. Brown was Member of Parliament (MP) for Dunfermline East from 1983 to 2005 and for Kirkcaldy and Cowdenbeath from 2005 to 2015. He has served as United Nations Special Envoy for Global Education since 2012, and he was appointed as World Health Organization Ambassador for Global Health Financing in 2021.
