The Queen is celebrating her 96th birthday on Thursday in Sandringham.
Britain’s longest-reigning monarch travelled by helicopter to her Norfolk estate, where she will be joined by family and friends.
She is expected to stay in a cottage on the estate particularly liked by her late husband, Prince Philip.
A photograph has been released to mark the birthday, 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.
Birthday wishes have been sent by Prime Minister Boris Johnson and Labour leader Sir Keir Starmer and gun salutes will be fired.
