A lucky 10,000 people who won tickets to the Jubilee concert in a public ballot were also invited to a picnic in the grounds of Buckingham Palace.

The picnic was put together by Heston Blumenthal, who worked with the Queen's head chef to create a lunch which reflected Britain's heritage.

He told the BBC's Lizo Mzimba what the hamper contained.
