Britain's Duke of Edinburgh has died, Buckingham Palace has announced.
Philip (99) was the longest-serving consort in British history.
The duke and Queen Elizabeth were married for more than 70 years.
He officially retired from public engagements in the summer of 2017.
The Palace said in a statement: “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.
“His Royal Highness passed away peacefully this morning at Windsor Castle.
“Further announcements will made in due course.
“The Royal Family join with people around the world in mourning his loss.”
Philip had returned to Windsor Castle on March 16th to be reunited with the Queen after spending a month in hospital – his longest ever stay.
He initially received care for an infection but then underwent heart surgery for a pre-existing condition.
The duke had looked gaunt as he was driven away from King Edward VII’s Hospital in central London, having been pushed in a wheelchair to the waiting car.
Philip was just two months away from his 100th birthday in June.
He spent much of the pandemic staying with the queen at Windsor in HMS Bubble – the nickname given to the couple’s reduced household of devoted staff during lockdown.
