Royals Queen Elizabeth Is 'in Great Spirits' as She Makes Surprise Appearance at Windsor Horse Show The Queen, 96, watched the race from her car before walking slowly to her seat in the stands By Simon Perry Published on May 13, 2022 07:05 AM Share Tweet Pin Email Queen Elizabeth made a surprise appearance among the crowds at the Windsor Horse Show on Friday. The monarch, 96, was driven the short distance from her Windsor Castle home to see three of her fell ponies take part in the race. She watched the event from the comfort of her Range Rover — and was overjoyed to see one of them, Balmoral Leia, win the Highland Class. The Queen, who missed the State Opening of Parliament on Tuesday due to "episodic mobility problems," was all smiles during the outing.
