Prince Philip, husband of Queen Elizabeth, passed away on Friday morning, Buckingham Palace confirmed.

In a Twitter statement posted on the Royal Family handle, it 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 statement added.

The Prince was 99 at the time of his death.

The Palace said in its statement that further announcements will made in due course.

Prince Philip had been admitted to the hospital in February for a month where he was treated for a heart problem.

The 28-night stay had been his longest spell in hospital after he was first admitted to the King Edward VII Hospital on February 16 before moving to a National Health Service (NHS) specialist St. Bartholomew's Hospital two weeks later, where he underwent a procedure for a pre-existing heart condition.

Prince Philip and the Queen had spent most of the lockdown at Windsor Castle in England with a small group of household staff, nicknamed HMS Bubble . The couple, who have been married for 73 years, received their first Covid-19 jabs together in January.

In 2011, Prince Philip was taken to hospital by helicopter from Sandringham after suffering chest pains as the royal family was preparing for Christmas. He was treated for a blocked coronary artery at Papworth Hospital in Cambridgeshire and had a stent fitted.

The Duke retired from official royal duties in 2017 after years of service in the armed forces and then as a consort to the monarch, with several charity endeavours.
