William, Charles's eldest son and heir to the throne, was named Prince of Wales, while the children of his second son Harry, no longer a working royal, were officially named as prince and princess earlier this week.

Edward's new title comes after he took on a number of his father's roles, including at The Duke of Edinburgh Award charity which encourages young people to undertake challenges.

"The new Duke and Duchess of Edinburgh are proud to continue Prince Philip’s legacy of promoting opportunities for young people of all backgrounds to reach their full potential," Buckingham Palace said, referring to Edward's wife Sophie.

Philip had held the title of the Duke of Edinburgh since his marriage to the then Princess Elizabeth in 1947 until his death in 2021.
