The Queen and the Duke of Edinburgh were in Surrey watching horse racing at the Epsom Derby on the 54th anniversary of her coronation.

They joined thousands of race goers hoping to see jockey Frankie Dettori win the Derby at his 15th attempt.
A 41-gun salute was fired at Green Park at midday and a 62-gun salute at the Tower of London at 1300 BST.
Although the Queen succeeded to the throne on 6 February, 1952, she was not crowned until 16 months later.
At the ceremony on 2 June 1953, the Queen wore a gown incorporating all the floral symbols of the UK and Commonwealth.
The day of the Queen's coronation was chosen because the weather was likely to be sunny, although the wet weather that materialised did not deter huge crowds from flocking to London.
About 20 million people across Britain watched the proceedings on television after cameras were allowed inside Westminster Abbey.
The ceremony was held in front of 7,600 people, among them a four-year-old Prince Charles.
The coronation was marked by street parties across the UK and festivities around the world.
