Charles III, born November 14, 1948, is King of the United Kingdom and 14 other Commonwealth realms. He acceded to the throne on September 8, 2022 upon the death of his mother, Queen Elizabeth II, who was the longest-reigning British monarch in history, reigning for more than 70 years. At 73 years of age, Charles is the oldest person ever to assume the British throne.

In his first televised address following his accession to the throne, Charles III said:

"Queen Elizabeth’s was a life well lived; a promise with destiny kept and she is mourned most deeply in her passing. That promise of lifelong service I renew to you all today.”

However, some say the King should abdicate in favour of his eldest son and heir apparent, William, Prince of Wales:

... some royal fans have called for Charles to abdicate in favour of making his eldest son William the king.

Not only is William younger and more popular, his wife Catherine, Duchess of Cambridge is also considered by some to be a more favourable choice for Queen Consort than Camilla.
