Edward and Sophie's royal titles
The Duke and Duchess of Edinburgh were formerly known as the Earl and Countess of Wessex. On Edward's 59th birthday in March 2023, the King made him the Duke of Edinburgh.
Buckingham Palace said in a statement at the time: "His Majesty The King has been pleased to confer the Dukedom of Edinburgh upon The Prince Edward, Earl of Wessex and Forfar, on the occasion of His Royal Highness’s 59th birthday. The title will be held by Prince Edward for His Royal Highness’s lifetime.
"The Dukedom was last created for Prince Philip in 1947, upon his marriage to Princess Elizabeth, who held the title of Duchess of Edinburgh before acceding to the throne in 1952.
"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."
The late Duke of Edinburgh, who died in April 2021, had always wanted his youngest son Edward to inherit his title, but the decision ultimately was down to Charles as King.
The dukedom – which in the past has been hereditary – will not, however, pass down to James when Edward dies.
James has taken on his father's former title, and is now James, Earl of Wessex.
