The Prime Minister

The Prime Minister is appointed by the Sovereign as a primus inter pares, or first among equals, within the Privy Council, in a chairman-style rôle. The office of Prime Minister is also always combined with that of Lord High Constable, which is a Great Officer of State.
The Prime Minister is Head of Government – and in this place manages and oversees the executive part of national government, as directed by the Sovereign, Parliament, the Privy Council, and by settled law.
His appointment is formally made by the Sovereign on the advice of other Ministers and the Houses of Lords and Commons; he is, however, subject to votes of confidence at any time. The position is not a powerful one because it is not intended to be a catalyst for radical change; the whole of the state structure, indeed, is designed for the efficient and smooth running of public services, rather than as a platform for partisan theatre.
