On Saturday, Prince Charles Philip Arthur George was formally proclaimed King and is now known as Charles III.

On Saturday morning at St. James’ Palace, the Accession Council issued the proclamation.

The Archbishop of Canterbury, the prime minister, other senior parliamentarians, and members of the Royal Family make up the Accession Council.

To formally crown Charles King, they had met in St. James’ Palace, the sovereign’s official abode.

Penny Mordaunt made the official announcement of Queen Elizabeth II’s passing before proclaiming himself king.

The announcement of the new monarch was read out in front of former UK prime ministers Gordon Brown, David Cameron, Boris Johnson, and Theresa May.

The proclamation had been read as follows by the clerk of the council: “Whereas it pleased Almighty God to call to his mercy our late sovereign lady Queen Elizabeth the Second of blessed and glorious memory, by whose demise the crown of Great Britain and Northern Ireland is solely and rightfully come to Prince Charles, Philip Arthur George.

“Therefore, we, the lords spiritual and temporal of this realm, and members of the House of Commons along with other members of her late majesty’s privy council and representatives of the realms and territories, Alderman, citizens of London, and others, publish and proclaim that the Prince Charles Philip Arthur George is now by the death of our late sovereign of happy memory, becomes our only lawful and happy liege Lord.

Charles III, by the grace of God, King of the United Kingdom of Great Britain and Northern Ireland and of his other realms and territories, head of the Commonwealth, and Defender of the Faith, to whom we humbly acknowledge all faith and obedience, implores God, by whom Kings and Queens do reign, to grant his majesty a long and happy reign over us.

Prior to the signing of the documents, the roughly 200 individuals present in the room joined the clerk in saying, “God Save the King.”

The event’s host, Lord President Mordaunt, specified the further steps for the Proclamation, including ordering that it be read in London, Edinburgh, Cardiff, and Belfast and beginning the gun salutes in Hyde Park and the Tower of London as soon as the King is declared.
