The monarch is regarded internally as the absolute authority, or "sole prerogative", and prerogative the source of many of the executive powers of the British government. Some of the government's executive authority is theoretically and nominally vested in the sovereign and is known as the royal prerogative. The monarch acts within the constraints of convention and precedent, exercising prerogative only on the advice of ministers responsible to Parliament, often through the prime minister or Privy Council. In practice, prerogative powers are exercised only on the prime minister's advice – the prime minister, and not the sovereign, has control. The monarch holds a weekly audience with the prime minister; no records of these audiences are taken and the proceedings remain fully confidential. The monarch may express his or her views, but, as a constitutional ruler, must ultimately accept the decisions of prime minister and the Cabinet (providing they command the support of the House). In Bagehot's words: "the sovereign has, under a constitutional monarchy ... three rights – the right to be consulted, the right to encourage, the right to warn."Although the royal prerogative is extensive and parliamentary approval is not formally required for its exercise, it is limited. Many Crown prerogatives have fallen out of use or have been permanently transferred to Parliament. For example, the monarch cannot impose and collect new taxes; such an action requires the authorisation of an Act of Parliament. According to a parliamentary report, "The Crown cannot invent new prerogative powers", and Parliament can override any prerogative power by passing legislation.The royal prerogative includes the powers to appoint and dismiss ministers, regulate the civil service, issue passports, declare war, make peace, direct the actions of the military, and negotiate and ratify treaties, alliances, and international agreements. However, a treaty cannot alter the domestic laws of the United Kingdom; an Act of Parliament is necessary in such cases. The monarch is the Head of the Armed Forces (the Royal Navy, the British Army, and the Royal Air Force), and accredits British High Commissioners and ambassadors, and receives heads of missions from foreign states.It is the prerogative of the monarch to summon and prorogue Parliament. Each parliamentary session begins with the monarch's summons. The new parliamentary session is marked by the State Opening of Parliament, during which the sovereign reads the Speech from the throne in the Chamber of the House of Lords, outlining the Government's legislative agenda. Prorogation usually occurs about one year after a session begins, and formally concludes the session. Dissolution ends a parliamentary term, and is followed by a general election for all seats in the House of Commons. A general election is normally held five years after the previous one under the Fixed-term Parliaments Act 2011, but can be held sooner if the prime minister loses a motion of confidence, or if two-thirds of the members of the House of Commons vote to hold an early election.
