In the British system of government, the leader of the party with a majority in Parliament
is the Prime Minister. After an election, the monarch asks this person to "form a government." The word "government" has a different meaning than in the United States. It refers to a cabinet of ministers chosen from Parliament
who enjoy the support of a majority in the House of Commons
. The Prime Minister thus becomes both the head of the legislative branch and the chief executive of the national government.
