Prince Philip, Queen Elizabeth II’s husband, has died aged 99, Buckingham Palace has announced.
A statement issued by the palace just after midday spoke of the Queen’s “deep sorrow” following his death at Windsor Castle on Friday morning.
The Duke of Edinburgh, the longest-serving royal consort in British history, was at the Queen’s side for more than her six decades of reign.
Boris Johnson said he “inspired the lives of countless young people”.
“It is with deep sorrow that Her Majesty The Queen announces the death of her beloved husband,” the palace said.
“The Royal Family join with people around the world in mourning his loss.”
Speaking at Downing Street, the prime minister said that the duke had “earned the affection of generations here in the United Kingdom, across the Commonwealth, and around the world”.
