The image was taken during the filming of a special BBC programme being screened on Sunday marking Commonwealth Day, featuring the royal family.
The Queen was photographed in St George’s Hall at Windsor Castle wearing a delphinium blue dress and jacket of silk and wool cloque by Angela Kelly.
On her left shoulder the head of state wears the chrysanthemum brooch, made from sapphires and diamonds set in platinum.
The Queen was also pictured wearing the item when she was photographed with the Duke of Edinburgh to mark their 73rd wedding anniversary in November.
She also wore the brooch for images taken on her honeymoon with Philip at Broadlands in Hampshire in 1947, and again in pictures released to mark the couple’s 60th wedding anniversary in 2007.
