King Charles III granted his youngest brother, Prince Edward, the Duke of Edinburgh title, held by Prince Philip until his death, Buckingham Palace announced. The announcement came on the Prince's 59th birthday.
The title of the Earl of Wessex Edward, changed to the Duke of Edinburgh, and the title of his wife, Sophie, the Countess of Wessex, changed to the Duchess of Edinburgh.
Buckingham Palace said in a statement on Friday: "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."
Duke of Edinburgh passed to Prince Philip after his marriage to Princess Elizabeth, who later became Queen Elizabeth II, and held it until his death in 2021.
After that, the title reverted to the hands of the monarch, Queen Elizabeth, and the Crown Prince Charles inherited the title but didn't use it.
After the death of Queen Elizabeth, Charles came to the throne and passed the title to his brother.
It is expected that Prince Edward, and his wife Sophie will attend an event at the Scottish capital to attend an event marking the first anniversary of the War in Ukraine.
The couple will have a lot of responsibilities, including supervising Prince Philip's awards, and have a lot of Royal engagements, and a higher rank as Prince Andrew, the Duke of York, is no longer a working Royal member.
"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."
