London, Sep 10: For the first time in a televised ceremony, King Charles III was on Saturday officially proclaimed the new British monarch following the demise of his 96-year-old mother, Queen Elizabeth II who reigned for 70 years on the throne.

Charles, the Queen's first born, became king immediately after her death on Thursday, but a historic meeting formally confirmed his role on Saturday during the ceremony at St James's Palace, says the BBC.

The Accession Council, a body made up of senior politicians, judges and officials, proclaimed him as the monarch in the State Apartments.

Following the proclamation, the King formally announced the death of his "beloved mother, the Queen". King Charles III Proclaimed Britain's New Monarch in Historic Ceremony of Accession Council at St James's Palace in London (Watch Video).

"The whole world sympathises with me in the irreparable loss we've all suffered," he said.

"My mother gave an example of lifelong love and of selfless service. My mother's reign was unequalled in its duration, dedication and devotion. Even as we grieve, we give thanks for this most faithful life.

"I am deeply aware of this deep inheritance and of the grave duties and responsibilities which are now passed to me," the BBC quoted Charles as saying. Charles III Proclaimed New Monarch of The United Kingdom And Commonwealth Realms.

Also in attendance at the ceremony were Prime Minister Liz Truss, and former premiers Gordon Brown, David Cameron, Boris Johnson and Theresa May, as well as Archbishop Justin Welby and Prince William.

Before Charles was named the King, the death of the Queen was formally announced.
