Queen Elizabeth II’s husband Prince Philip, has died on Friday at age 99.
He was due to celebrate his 100th birthday in June 2021.
Buckingham Palace announced that he died after recently spent more than a month in hospital and underwent a heart procedure.
“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,” it said in a statement.
“His Royal Highness passed away peacefully this morning at Windsor Castle.
“The Royal Family join with people around the world in mourning his loss.”
The palace added that further announcements would be made “in due course”.
Fears over the health of the Duke of Edinburgh, as he was formally known, had been heightened after he recently spent a month in hospital for treatment.
He left the hospital on March 16 following what was described as a successful procedure for a pre-existing condition and treatment for an unspecified infection.
Philip had returned to Windsor Castle, west of London, where he had been isolating with the queen — Britain’s longest-serving monarch — since the start of the coronavirus pandemic last year.
