The Duke of York, Prince Andrew’s military titles and royal patronages have been returned to the Queen, Buckingham Palace has said.
The 61-year-old will also stop using the style His Royal Highness in an official capacity, a royal source said.
It comes as he faces a US civil action over sexual assault allegation.
Buckingham Palace said in a statement: “With the Queen’s approval and agreement, the Duke of York’s military affiliations and Royal patronages have been returned to the Queen.
“The Duke of York will continue not to undertake any public duties and is defending this case as a private citizen.”
All Prince Andrew’s roles have been returned to the Queen with immediate effect, and will be redistributed to other members of the Royal Family, reports said.
Like Harry and Meghan, Prince Andrew retains his title HRH but will not use it in any official capacity.
The duke had a 22-year career in the Royal Navy, and served as a helicopter pilot during the Falklands War.
On Thursday, a letter – released by anti-monarchy pressure group Republic – was signed by more than 150 Royal Navy, RAF and Army veterans asking the Queen to strip Prince Andrew of his eight British military titles.
Lt Stuart Hunt, who served in The 1st Royal Tank Regiment and signed the letter, welcomed the prince losing his military titles but suggested the matter should have been resolved sooner.
The 52-year-old told the PA News Agency: “It’s an unsavoury business… I’m just glad he’s not associated with the military now.
“Whether he’s guilty or not, he has brought things into disrepute… He’s not fit to serve in an honorary rank. He has forgone that right by getting into this sort of situation.”
