While the new Sovereign succeeds to the throne as soon as his or her predecessor dies, they are formally proclaimed at the Accession Council, the Royal Family said.
His Majesty The King was formally proclaimed at the Accession Council, held at St James’s Palace.
This historic ceremony, filmed for the first time, started with a meeting held by the Privy Council. The Queen Consort and Prince of Wales were present.
In the meeting, the Privy Council officially proclaimed His Majesty as King Charles III.
The King was present for the second part of the ceremony, where he held his first Privy Council meeting.
His Majesty made a personal declaration and read and signed an oath to uphold the security of the Church in Scotland.
After the Accession Council, the Principal Proclamation was made from the balcony overlooking Friary Court at St James’s Palace.
The Proclamation was read by the Garter King of Arms, accompanied by the Earl Marshal, other Officers of Arms and the Serjeants at Arms.
The Queen of England, Queen Elizabeth II, head of the Commonwealth and monarch of 15 countries, died on Thursday at 96 after 70 years on the throne.
