Prince Philip, husband of Queen Elizabeth and a leading figure in the British royal family for almost seven decades, has died aged 99, Buckingham Palace said on Friday.
The Duke of Edinburgh, as he was officially known, had been by his wife's side throughout her 69-year reign, the longest in British history, during which time he earned a reputation for a tough, no-nonsense attitude and a propensity for occasional gaffes.
"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 join with people around the world in mourning his loss."
