Dissolution of the Parliament of the United Kingdom in the context of "House of Commons of the United Kingdom"

The Dissolution and Calling of Parliament Act 2022 (c. 11) is an act of the Parliament of the United Kingdom that repealed the Fixed-term Parliaments Act 2011 and reinstated the prior constitutional situation, by reviving the power of the monarch to dissolve and summon parliament. As the monarch exercises this power at the request of the prime minister, this restored the power of the prime minister to have a general election called at a time chosen by the prime minister.

It was originally drafted as the Fixed-term Parliaments Act 2011 (Repeal) Bill. Announced formally in the 2021 State Opening of Parliament, it received its first reading on 12 May 2021 and received Royal Assent on 24 March 2022. It was introduced by Chancellor of the Duchy of Lancaster, Michael Gove.

The Lascelles Principles are a constitutional convention in the United Kingdom beginning in 1950, under which the sovereign can refuse a request from the prime minister to dissolve Parliament if three conditions are met:

1. if the existing Parliament is still "vital, viable, and capable of doing its job",
2. if a general election would be "detrimental to the national economy", and
3. if the sovereign could "rely on finding another prime minister who could govern for a reasonable period with a working majority in the House of Commons".

The convention was in abeyance from 2011 to 2022, when the sovereign's prerogative power to dissolve Parliament was removed by the Fixed-term Parliaments Act 2011. Following passage of the Dissolution and Calling of Parliament Act 2022, which repealed the Fixed-term Parliaments Act, these principles are thought to have been revived.

Counsellors of State are senior members of the British royal family to whom the monarch can delegate royal functions through letters patent under the Great Seal, to prevent delay or difficulty in the dispatch of public business in the case of their illness (except total incapacity) or of their intended or actual absence from the United Kingdom.

Counsellors of state may carry out "such of the royal functions as may be specified in the Letters Patent". In practice, this means most of the monarch's official duties, such as attending Privy Council meetings, signing routine documents and receiving the credentials of new ambassadors to the Court of St James's. However, by law, counsellors of state cannot grant ranks, titles or peerages. They also, by the terms of the letters patent, cannot deal with a number of core constitutional functions, such as Commonwealth matters, the dissolution of Parliament (except on the monarch's express instruction) and the appointment of prime ministers. A rare example occurred on 7 February 1974 of the Proclamation of the Dissolution of Parliament being promulgated by Queen Elizabeth The Queen Mother and Princess Margaret as counsellors of state, on the express instructions of Queen Elizabeth II.
