Prince Philip’s official cause of death has been revealed as “old age,” according to his death certificate.
No other medical conditions were identified as contributing factors in The Duke of Edinburgh’s death, according to the document obtained by The Telegraph.
Philip died at the age of 99 on April 9 as the oldest-ever male member of the British royal family.
At the time, Buckingham Palace said: “His Royal Highness passed away peacefully this morning at Windsor Castle.”
The Duke’s death certificate was certified by Sir Huw Thomas, who heads the royal medical household, The Telegraph reported.
“Old age” can be listed as a cause of death for patients over 80 who’s health gradually declines, as observed by their long-term doctor, the report said.
On the death certificate, Philip’s first occupation is listed as Naval Officer.
His second is “husband of Her Majesty Queen Elizabeth II, The Sovereign.”
