One day after King Charles’ accession, he appeared on television to make his first public address to the nation in order to pay tribute to his mother, the late Queen.
It was in this speech that he also confirmed that his eldest son and daughter-in-law - then styled as the Duke and Duchess of Cornwall and Cambridge - would be known as the Prince and Princess of Wales.
As a result, Prince William became the 27th Prince of Wales and was granted the additional titles of the Duke of Cornwall, the Earl of Chester, the Duke of Rothesay, the Earl of Carrick, the Baron of Renfrew, Lord of the Isles and Prince and Great Steward of Scotland.
