The Queen was greeted by cheers and applause as she arrived for a day at the races at Royal Ascot.
Shouts of "God save the Queen" rang out around the Berkshire racecourse's parade ground as she entered in a traditional horse-drawn royal carriage procession.
The Queen was accompanied by the Duke of Edinburgh, who appeared fit and well following his recent stay in hospital that caused him to miss part of the Diamond Jubilee celebrations.
The Queen wore a dress and coat in pale blue by Stewart Parvin with a matching hat by Rachel Trevor-Morgan. She and the Duke were joined by the Viscount Ullswater and Lord Vestey.
