who elects head of state government in great britain
Government of the United Kingdom 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.[4] The government ministers all sit in Parliament, and are accountable to it. The government is dependent on Parliament to make primary legislation,[5] 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.[6]
Parliamentary system Countries with parliamentary systems may be constitutional monarchies, where a monarch is the head of state while the head of government is almost always a member of parliament (such as the United Kingdom, Denmark, Sweden and Japan), or parliamentary republics, where a mostly ceremonial president is the head of state while the head of government is regularly from the legislature (such as Ireland, Germany, India and Italy). In a few parliamentary republics, such as Botswana, South Africa, and Suriname, among some others, the head of government is also head of state, but is elected by and is answerable to parliament. In bicameral parliaments, the head of government is generally, though not always, a member of the lower house.
