Prince Philip, the husband of Queen Elizabeth II, has died aged 99, Buckingham Palace said on Friday.
“It is with deep sorrow that Her Majesty The Queen announces the death of her beloved husband, His Royal Highness The Prince Philip, Duke of Edinburgh,” the palace said in a statement.
“His Royal Highness passed away peacefully this morning at Windsor Castle. Further announcements will be made in due course. The Royal Family joins with people around the world in mourning his loss.”
The Duke of Edinburgh, as he was officially known, had spent four weeks in a UK hospital earlier this year to receive treatment for an infection and have a heart procedure, but returned to Windsor in early March.
He had been by the queen’s side throughout her 69-year reign, the longest in British history.
“He has, quite simply, been my strength and stay all these years,” the queen said in a rare personal tribute to him made in a speech marking the pair’s 50th wedding anniversary in 1997.
The couple married in 1947, five years before Queen Elizabeth II succeeded to the throne.
