The position of prime minister,[REF] the UK's head of government,[REF] belongs to the person most likely to command the confidence of the House of Commons; this individual is typically the leader of the political party or coalition of parties that holds the largest number of seats in that chamber.
Scotland, Wales and Northern Ireland each have their own government or executive, led by a First Minister (or, in the case of Northern Ireland, a diarchal First Minister and deputy First Minister), and a devolved unicameral legislature.
