Each Parliamentary year begins with the State Opening Ceremony, where the new King addresses the House of Lords about the executive's intended goals and policies.

The sovereign grants his or her Royal Assent to the bills passed by the House of Lords and the Commons, however this process is effectively now just a rubber stamping one since Queen Anne was the last monarch to refuse the Royal Assent to a bill in 1707.

The Prime Minister who has the backing of the majority of MPs is officially appointed by the new King. The Head of State summons the party's leader to Buckingham Palace to form the government after the party wins the general election. On the Prime Minister's recommendation, the monarch also formally dissolves a government before elections at the national level.

The newly elected British monarch will also preside over the Commonwealth of Nations, an organisation born out of the former British empire. There are 56 autonomous countries in it, and there are 2.4 billion people living there.
