The Government is formed by the party, which wins most seats at a general election, or which has the support of a majority of the members in the House of Commons. The leader of the majority party is Prime Minister. The Queen must appoint him. Then he forms his Cabinet of about 20 Ministers. The majority of the Ministers are members of the House of Commons. All the Ministers are appointed by the Queen on the recommendation of the Prime Minister.
The role of the monarch in the government is limited to acting on the advice of Prime Minister and Ministers.
A modern British Government consists of over ninety people, of whom about thirty are heads of departments, and the rest are their assistants. The Covernment controls and arranges the business of the House of Commons. As the initiator of policy, it dictates what action it wishes Parliament to take.
The head of the Government is the Cabinet of Ministers with Prime Minister having the leading position. The Cabinet determines policies, controls government and co-ordinates government departments.
The Prime Minister forms the Cabinet, gives functions to the Ministers, informs the Queen about the general business of the Government, and determines the general political line of the Government.
