His Majesty King Charles III of the United Kingdom of Great Britain and Northern Ireland is proclaimed King.
Council proclaiming a new British monarch
In the United Kingdom, the Accession Council is a ceremonial body which assembles in St James’s Palace in London upon the death of a monarch to make formal proclamation of the accession of the successor to the throne. Under the terms of the Act of Settlement 1701, a new monarch succeeds automatically (demise of the Crown). The proclamation merely confirms by name the identity of the new monarch and formally announces the new monarch’s regnal name.
