Proclamation of accession of Charles III

became King of the United Kingdom and of 14 other Commonwealth realms upon the death of his mother, Elizabeth II, on 8 September 2022. Royal succession in the realms occurs immediately upon the death of the reigning monarch. The formal proclamation in Britain occurred on 10 September 2022, at 10:00 BST, the same day on which the Accession Council gathered at St James's Palace in London. The other realms, including most Canadian provinces and all Australian states, issued their own proclamations at times relative to their time zones, following meetings of the relevant privy or executive councils. While the line of succession is identical in all the Commonwealth realms, the royal title as proclaimed is not the same in all of them.

United Kingdom

The proclamation occurred on 10 September 2022 at 10:00am BST at St James's Palace in London. Even though all 700 members of the Privy Council were eligible to attend the Accession Council, only 200 were summoned due to limitations of space.
Out of the King's presence, the Lord President of the Council had the clerk of the Council read the Accession Proclamation, which in addition to announcing the accession and pledging loyalty, formally introduced the King's new regnal name: Charles III. The proclamation was signed by Queen Camilla, the new queen consort; Prince William, the new Prince of Wales; Justin Welby, the archbishop of Canterbury; Brandon Lewis, the lord chancellor; Stephen Cottrell, the archbishop of York; the Duke of Norfolk, the earl marshal; Penny Mordaunt, the lord president; and Liz Truss, the then-new prime minister. The lord president then read the orders of council on issues dealing with the public proclamations and gun salutes at Hyde Park and the Tower of London.
The Privy Council was then summoned to attend the King for the second part of the council, where he delivered a personal address regarding the Queen's death. He took an oath to preserve the independence of the Church of Scotland, which was reaffirmed by signing two documents as Queen Camilla and the Prince of Wales witnessed his signature. At the conclusion of the ceremony, privy counsellors signed the proclamation. A minor incident during the signing, in which the King showed visible frustration at there being too many items on his under-sized table, went viral online.
Charles III's Accession Council was the first to be televised and the first to be streamed online. At 11:00, 21-gun salutes at the Tower of London, Cardiff Castle, Edinburgh Castle, Castle Cornet in Guernsey, Gibraltar, and naval bases and stations at sea marked the accession of Charles III. After the proclamation ceremony, the King greeted crowds outside Buckingham Palace.
When the Parliament of the United Kingdom met, members swore allegiance to the new king and expressed condolences for the late Queen's death. Most parliamentary activities were suspended for 10 days. At 15:30, the king hosted the prime minister and the cabinet for an audience. On the same day, the proclamation of the accession was issued by the devolved governments of Scotland, Wales and Northern Ireland.
