The Government of the United Kingdom (Welsh: Llywodraeth y Deyrnas Unedig), formally referred to as Her Majesty's Government, is the central government of the United Kingdom of Great Britain and Northern Ireland. It is also commonly referred to as simply the UK Government or the British Government.
The government is led by the Prime Minister, who selects all the remaining ministers. The prime minister and the other most senior ministers belong to the supreme decision-making committee, known as the Cabinet. The government ministers all sit in Parliament, and are accountable to it. The government is dependent on Parliament to make primary legislation, and since the Fixed-terms Parliaments Act 2011, general elections are held every five years to elect a new House of Commons, unless there is a successful vote of no confidence in the government or a two-thirds vote for a snap election (as was the case in 2017) in the House of Commons, in which case an election may be held sooner. After an election, the monarch (currently Queen Elizabeth II) selects as prime minister the leader of the party most likely to command the confidence of the House of Commons, usually by possessing a majority of MPs.
