The monarch has since released a photo to mark the celebratory occasion, showing the Queen with two ponies and reflecting her lifelong interest in horses.
The picture was taken at Windsor Castle, where the Queen now mostly stays, and shows her with two Fell ponies, who will appear in the forthcoming Royal Windsor Horse Show.
The Duke and Duchess of Cambridge wished the Queen happy birthday on Twitter, calling the monarch an “inspiration to so many across the UK, the Commonwealth and the world”.
Prince Harry suggested in a US TV interview that the Queen might be downplaying this latest milestone, saying that “after a certain age you get bored of birthdays”.
