Here are reactions from major public figures in Britain and around the world.

UK PRIME MINISTER BORIS JOHNSON

"We remember the Duke ... above all for his steadfast support for Her Majesty the Queen, not just as her consort, by her side, every day of her reign, but as her husband, has strength and stay of more than 70 years. And it is to Her Majesty, and her family, that our nation's thoughts must turn today."

"I join with the rest of the United Kingdom and the Commonwealth in mourning the loss of His Royal Highness Prince Philip, The Duke of Edinburgh, and give thanks to God for his extraordinary life of dedicated service."

"On the occasions when I met him, I was always struck by his obvious joy at life, his enquiring mind and his ability to communicate to people from every background and walk of life. He was a master at putting people at their ease and making them feel special."

UK OPPOSITION LABOUR PARTY LEADER KEIR STARMER
