Leader of the Opposition (UK)

The Leader of the Opposition in the United Kingdom parliament is the leader of the political party which is the best-placed to 'shadow' the government's activities and hold it to account. Usually, the Opposition Leader is the head of the largest minority party, i.e. the one with most seats after the government, and also appoints a Shadow Cabinet of senior Opposition politicians. Since December 2005 the Leader of the Opposition has been David Cameron.

When the Leader of the Opposition's party wins a general election, it is expected that he or she will become the next Prime Minister, and is invited by the Head of State to form a new government. In contrast, a new Leader of the Opposition emerges immediately, without any formal ceremony - for example, when John Major resigned as Prime Minister in 1997 following an election defeat, he left Buckingham Palace as the Leader of the Opposition, as his party was now second-placed in terms of number of seats in Parliament.

The office of Leader of the Opposition and their party receive the largest share of 'Short money' (state funding); for example, in 2005-2006 the current Opposition party, the Conservatives, received over £4 million in various expenses, with money also spent on vehicles and security. In other words, in the British parliamentary system, the public pays political parties to oppose the elected government.

As a potential Prime-Minister-in-waiting, the Leader of the Opposition frequently appears in the media, commenting and criticising on the government's activities, and presenting alternative proposals that might form policy in their own future government. Their most prominent parliamentary duty is the weekly appearance at a debate known as 'Prime Minister's Questions', in which the Leader of the Opposition faces the Prime Minister over the floor of the House of Commons. The Opposition Leader asks six questions, which are not made available to the Prime Minister's office in advance. Another way in which parliamentary activities present the Opposition Leader as a potential Prime Minister is at the State Opening of Parliament, where they join the Prime Minister at the head of a procession from the Commons to the House of Lords.
