Britain's Prince Philip, husband of Queen Elizabeth, dies aged 99

Prince Philip, the 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 that 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.”

A Greek prince, Philip married Elizabeth in 1947. He went on to play a key role in modernising the monarchy in the post-World War Two period, and behind the walls of Buckingham Palace was the one key figure the queen could turn to and trust.

“He has, quite simply, been my strength and stay all these years,” Elizabeth said in a rare personal tribute to Philip, made in a speech marking their 50th wedding anniversary in 1997.

Philip spent four weeks in hospital earlier this year for treatment for an infection to have a heart procedure, but returned to Windsor in early March.
