Queen Elizabeth's husband Prince Philip dies at age 99

The Buckingham Palace announced in a statement on Friday that the husband of Britain's Queen Elizabeth II, Prince Philip, the Duke of Edinburgh, has passed away.

He was 99 years old — the longest-serving and oldest-ever consort of the United Kingdom's monarchy.

"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," the Palace said in a statement.

"His Royal Highness passed away peacefully this morning at Windsor Castle."

While the cause of death has yet to be revealed, Philip had been hospitalised over the past few years, most recently in February.

News of his death came after the monarchy was recovering from Prince Harry and Meghan Markle's explosive interview with Oprah Winfrey, where they levied harsh claims against the royal family.
