It comes after the Queen also indicated she was experiencing some mobility problems. In an ITV News video of her in-person audience, the monarch, who was standing with the aid of a walking stick, pointed to her left leg or foot, and commented: "Well, as you can see, I can't move."
Her Majesty is understood to have been feeling slightly stiff, rather than suffering from an injury or illness.
