LONDON, April 9 (Xinhua) -- Britain's Prince Philip, Queen Elizabeth II's husband, has died at the aged of 99, Buckingham Palace announced Friday.
"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. Further announcements will be made in due course. The Royal Family join with people around the world in mourning his loss," said the statement.
No official details have been announced yet about the Duke's funeral, but it is understood the Duke of Edinburgh will be given a royal ceremonial funeral rather than a state funeral according to his wishes, Sky News reported.
The flag at Buckingham Palace was lowered to half-mast and a notice was posted on the gates following the announcement of Prince Philip's death.
British Prime Minister Boris Johnson said in a statement: "It was with great sadness that a short time ago I received word from Buckingham Palace that His Royal Highness the Duke of Edinburgh has passed away at the age of 99."
"He was an environmentalist, and a champion of the natural world long before it was fashionable. With his Duke of Edinburgh awards scheme he shaped and inspired the lives of countless young people and at literally tens of thousands of events he fostered their hopes and encouraged their ambitions. We remember the Duke for all of this and above all for his steadfast support for Her Majesty the Queen," said the statement.
In May 2017, the 96-year-old duke retired from his own program of royal duties after carrying out more than 20,000 solo public engagements.
The duke left hospital last month after a month-long treatment. He underwent a procedure for a pre-existing heart condition, according to Buckingham Palace.
Prince Philip married Princess Elizabeth in 1947, five years before she became Queen, and was the longest-serving royal consort in British history. The couple had four children, eight grandchildren and 10 great-grandchildren.
Prince Philip was born in Greece's island of Corfu on June 10, 1921.
