Charles, Prince of Wales, automatically became the new British monarch after the death of Queen Elizabeth II on Sept. 8.
According to the official website of the Buckingham Palace, 73-year-old Charles and his wife Camilla will remain at Balmoral Castle, where the Queen died, and will return to London on Sept. 9.
UK Prime Minister Liz Truss, as well as Clarence House (the new king’s official residence) have announced that Charles will be known by the regnal name of King Charles III.
Under the protocol surrounding the accession of a new monarch, Charles succeeds to the throne immediately on the death of the monarch, the Reuters news agency reported.
An Accession Council is convened as soon as possible, usually within 24 hours, and held at St James’s Palace, the senior royal palace of the sovereign, though no longer their usual place of residence, to proclaim the successor.
After the death of Queen Elizabeth II, Charles made a statement published on the Royal Family’s Twitter account.
“The death of my beloved Mother, Her Majesty The Queen, is a moment of the greatest sadness for me and all members of my family,” Charles said.
“We mourn profoundly the passing of a cherished Sovereign and a much-loved Mother. I know her loss will be deeply felt throughout the country, the Realms and the Commonwealth, and by countless people around the world.”
“During this period of mourning and change, my family and I will be comforted and sustained by our knowledge of the respect and deep affection in which The Queen was so widely held.”
Queen Elizabeth II died at Balmoral Castle in Scotland on Sept. 8. Her 70-year reign is the longest in the history of the British monarchy.
