The Queen has attended the finale of a four-day horse show that celebrated her 70 years on the throne and drew a star-studded cast including actors Tom Cruise and Dame Helen Mirren.
The 96-year-old monarch, wearing a grey shawl, was driven to the outdoor spectacle in the grounds of Windsor Castle where she was welcomed by two Royal Canadian Mounted Police officers who helped her from her Range Rover to cheers from crowds.
"She's just a woman that I greatly admire," Cruise said before the event. "I think she's someone who has tremendous dignity and I admire her devotion. What she's accomplished has been historic."
Queen Elizabeth has attended every Royal Windsor Horse Show since its inception 79 years ago, reflecting her keen interest in horse racing and breeding.
In a photograph marking her 96th birthday in April, she was pictured with two fell ponies.
The Queen has been seen in public on only a few occasions after she spent a night in hospital in October last year for an unspecified illness, after which she was told to rest by her doctors.
She has since carried out duties either remotely or in person at her Windsor Castle home and did not attend last week's state opening of parliament. Her son and heir to the throne, Prince Charles, read out the government's legislative agenda.
On Sunday, she used a small lift to help her get from her car to her seat, according to a reporter for ITV television which broadcast the event.
The horse show kicked off celebrations to mark the Queen's Platinum Jubilee which will culminate in four days of national events from June 2. She also attended the show on Friday.
On Thursday, it was announced that a lemon and Swiss roll amaretti trifle had been named as winner of a "Platinum Pudding" competition, beating 5000 other entries.
