A statement from Buckingham Palace said: “It is with deep sorrow that Her Majesty The Queen has announced 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 Duke was married to Queen Elizabeth II for more than 70 years and became the longest-serving consort in British history.
Flags on landmark buildings in Britain were being lowered to half-mast as a period of mourning was announced.
Prince Philip’s health had been slowly deteriorating for some time. He announced he was stepping down from royal engagements in May 2017, joking that he could no longer stand up. He made a final official public appearance later that year during a Royal Marines parade on the forecourt of Buckingham Palace.
