The flag at Buckingham Palace flies at half-mast this evening following the death of Prince Philip at the age of 99. A statement from the royal household announced the news shortly after midday, saying: "It is with deep sorrow that Her Majesty The Queen announces the death of her beloved husband." Shortly afterwards, the prime minister stood in Downing Street to acknowledge how the duke had "earned the affection of generations here in the United Kingdom, across the Commonwealth and around the world". Through the Duke of Edinburgh awards scheme, he had "shaped and inspired the lives of countless young people", Boris Johnson added.

A notice was posted on Buckingham Palace's gates following the announcement, while people laid floral tributes outside. Crowds also began to gather at Windsor Castle, although people were later asked not to congregate  in light of pandemic restrictions. The BBC's royal correspondent Nicholas Witchell described "a moment of real national sadness", which brings to an end an unparalleled 73 years as consort. As our obituary notes: "Prince Philip had no constitutional position. But no-one was closer to the monarchy, or of greater importance to the monarch." This special late edition of News Daily brings together the breadth of our coverage.

Tributes to Prince Philip are flooding in from monarchs, heads of state and PMs past and present around the world, from Sweden to India and New Zealand. The duke accompanied the Queen on hundreds of overseas visits. And in the words of Australian PM Scott Morrison: "He embodied a generation that we will never see again."  Spain's king and queen telegrammed "Dear Aunt Lilibet" to mourn the passing of "Dear Uncle Philip". And US President Joe Biden said in a statement with First Lady Jill Biden: "His legacy will live on not only through his family, but in all the charitable endeavours he shaped."

While the last three sovereign's consorts have lain in state - including the Queen Mother in 2002 - the Duke of Edinburgh will not, in line with his wishes. Prince Philip will instead lie at rest in Windsor Castle before a royal ceremonial funeral at St George's Chapel, says the College of Arms, which helps organise state occasions. Covid-19 meant the funeral plans - codenamed Forth Bridge - were revised, leaving the public "regretfully" requested not to attend. Flags will fly at half-mast on government buildings from now until 08:00 BST on the day after the funeral. More details are expected from Buckingham Palace in due course.
