SEE pictures as King Charles III officially becomes King at the historic Accession Council. 

The new monarch automatically became King following the death of his mother Queen Elizabeth II who passed away peacefully on Thursday aged 96.

However, the former Prince of Wales attended the Accession Council with the Privy Councillors which confirmed his role on Saturday morning.

The new monarch did not appear in the first half of the ceremony which was held at the State Apartments of St James’s Palace.

Historically, the entire Privy Council is summoned to the Accession Council for the tradition of proclaiming the new monarch.

However, on this occasion, only 200 were summoned to the Council with the rest asked to enter an annual ballot for a few remaining seats.

Queen Consort Camilla, the new Prince of Wales, and other Privy Councillors including the Prime Minister and Archbishop of Canterbury were in attendance.

Former prime ministers including Boris Johnson, Theresa May, David Cameron and Gordon Brown were also present at the monumental ceremony which has not taken place for 70 years.

Part I involved the Privy Council, without The King present where they proclaimed the new Sovereign.

They also formally approved various consequential Orders, including the arrangements for the Proclamation.

The Palace has explained what the second part involved: “Part II, is the holding by The King of His Majesty’s first Privy Council.

"The King will make his Declaration and read and sign an oath to uphold the security of the Church in Scotland and approve Orders in Council which facilitate continuity of government.”

Making his 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.”

Continuing the declaration, the new Monarch added: “To all of us as a family as to this kingdom, and the wider family of nations of which it is a part, my mother gave an example of lifelong love and of selfless service.

“My mother’s reign was unequalled in its duration, its dedication and its devotion.

“Even as we grieve, we give thanks for this most faithful life.”
