Prince Philip’s cause of death has been confirmed.
The 99-year-old royal death certificate confirmed that he died of “old age,”
The death was certified by Sir Huw Thomas, the head of the royal medical household and the physician to the Queen.
Typically, the term “old age” is acceptable as a cause of death if the patient is over 80 years old and if the physician has personally cared for them over a long period, The Telegraph reported.
Sir Huw Thomas has been caring for the Duke of Edinburgh and Queen Elizabeth since 2014.
He was again admitted to King Edward VII hospital on Feb. 16 to undergo a few days of observation and rest after “feeling unwell” and being “treated for an infection,” according to Buckingham Palace. This resulted in the prince’s longest ever hospital stay: 28 days before his passing on the 9th of April 2021 in his sleep at his home in Buckingham Palace.
