<P> 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 . </P>
