The Queen has watched the Derby at Epsom, having earlier driven on the race course to begin the first major event of the Diamond Jubilee weekend marking 60 years of her reign.
Racegoers cheered as the royal motorcade arrived at the winning post. Mezzo-soprano Katherine Jenkins then sang the national anthem.
Meanwhile, gun salutes echoed across London, Edinburgh, Cardiff and Belfast.
Street parties were held in numerous locations, with more planned later.
The Queen, wearing royal blue, was accompanied by the Duke of Edinburgh along with their sons the Duke of York and Earl of Wessex, and granddaughters Beatrice and Eugenie.
After some time in the royal box, she went to the paddock to inspect some of the horses running in the Diamond Jubilee Coronation Cup.
After the race she awarded the cup to Aidan O’Brien, the trainer of the winner St Nicholas Abbey, as well as meeting the horse’s owner and jockey.
About 130,000 people were estimated to be at Epsom, according to Surrey Police. (BBC)
