Prince Charles may use another name when he becomes the new king.

The Prince of Wales is the heir to the throne. According to a former Buckingham Palace spokesperson, Prince Charles is likely to use one of his middle names when he takes over the monarchy.

"He might choose one of his other names Philip, Arthur or George," Dickie Arbiter told Hello!

The publication noted that using another name once a royal takes over the throne is an uncommon practice among British Kings and Queens. For instance, Queen Elizabeth's father's first name was Albert but opted to be known as King George VI. King Edward VII's first name was also Albert, but to his family and friends, he was known as David, his last name.

Aside from being the new king, the Prince of Wales will inherit new titles including the Duke of Lancaster, Defender of the Faith, Supreme Governor of the Church of England, Head of the Commonwealth and King of other Realms and Territories.

"[Charles will] also be Lord of the Mann (Isle of Man) and Duke of Normandy. But generally, he'll only be known as King," Arbiter added.

Prince William and Kate Middleton will also hold new titles once Prince Charles becomes the new king. The Duke of Cambridge will be the new Prince of Wales and Duke of Cornwall. His wife, Middleton, will share his new titles. Basically, Middleton will inherit Camilla Parker Bowles and Princess Diana's titles. So, the mother of three would also be the new Princess of Wales and HRH The Duchess of Cornwall and Cambridge.

The Duke and Duchess of Cambridge's children will also inherit their titles. However, when Prince William takes over the throne from Prince Charles, Princess Charlotte will not automatically become the new Princess Royal.

"The title of Princess Royal is traditionally bestowed on the eldest daughter of the monarch," Duncan Larcombe told Town and Country, referencing to Princess Anne as the current Princess Royal. "It is a title that remains for life, so Princess Charlotte will have to wait at least until the death of the current Princess Royal."
