What does the king do in politics?

The King is the UK's head of state, but his political role is mostly ceremonial. He appoints the Prime Minister, opens Parliament, gives Royal Assent to new laws and meets the Prime Minister weekly. By convention he follows the government's advice and stays politically neutral.

The UK is a constitutional monarchy. Many government powers are exercised in the King's name, but ministers make the actual decisions. The King signs bills into law through Royal Assent. No monarch has refused assent since 1708. He also formally dissolves Parliament before elections and appoints ministers, judges and peers on advice. He also signs commissions, receives ambassadors and approves orders made by the Privy Council.

The King holds a private weekly audience with the Prime Minister. These meetings are confidential. The monarch has the right to be consulted, to encourage and to warn, but not to direct policy. He also reads the King's Speech, which the government writes. The King also hosts state visits and represents the country abroad, always on the government's advice.

The King keeps some reserve powers in theory, such as choosing a Prime Minister in an unclear hung parliament. In practice, conventions and advice from senior officials guide even these. The monarch does not vote and avoids public comment on political issues. He is also head of state in 14 other Commonwealth countries. This neutrality is seen as central to the monarchy's survival.
