Prince Philip

Duke of Edinburgh’s official cause of death revealed

Prince Philip, The Duke of Edinburgh

The Duke of Edinburgh’s official cause of death has been revealed on his death certificate.

The official document was obtained by The Telegraph and revealed that the 99-year-old Duke died from “old age.” This cause of death can be listed on the death certificates of those who are over the age of 80 and whose health gradually declined over time while being observed by their long-term doctor.

Sir Huw Thomas certified the death certificate; he serves as the head of the royal medical household.

His first occupation listed on the death certificate was that of “Naval Officer,” and his second occupation was listed as “Husband of Her Majesty Queen Elizabeth II, The Sovereign.”

Philip’s name was listed as “His Royal Highness The Prince Philip, Duke of Edinburgh formerly known as Prince Philippos of Greece and Denmark formerly known as Philip Mountbatten.” His death was registered four days after his passing by his private secretary, Brigadier Archie Miller-Bakewell, at the Royal Borough of Windsor and Maidenhead.

Prince Philip, Duke of Edinburgh, died on the morning of 9 April at Windsor Castle with The Queen by his side. Buckingham Palace announced his death that afternoon, saying:

“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. His Royal Highness passed away peacefully this morning at Windsor Castle … The Royal Family join with people around the world in mourning his loss.”

Prince Philip’s funeral took place on 17 April at St George’s Chapel.
