Charles III has been proclaimed as king at a ceremony at St James’s Palace.
Charles became king immediately following the death of his mother Queen Elizabeth II, but a historic meeting formally confirmed his role on Saturday.
The Accession Council, a body made up of senior politicians, judges and officials, proclaimed him as the monarch in the State Apartments.
It is the first time the historic ceremony has been televised.
The King himself was not present to begin with, but he attended the second part of the ceremony to hold his first Privy Council meeting.
Clerk of the Privy Council Richard Tilbrook proclaimed Charles “King, head of the Commonwealth, defender of the faith”, before declaring “God Save the King”.
The packed room, including the Queen Consort, the Prince of Wales and Prime Minister Liz Truss, repeated back the phrase.
Making his own declaration, the King said: “My lords, ladies and gentlemen, it is my most sorrowful duty to announce to you the death of my beloved mother the Queen.
“I know how deeply you, the entire nation, and I think I may say the whole world, sympathise with me in the irreparable loss we’ve all suffered.
“It is the greatest consolation to me to know the sympathy expressed by so many to my sister and brothers.
“And that such overwhelming affection and support should be extended to our whole family in our loss.”
