David Cameron heckled at the Olympic Park

David Cameron was told that he should be "ashamed of himself" as he was heckled by an official London 2012 volunteer during a speech marking the countdown to the start of the Olympics a month from now.

The Prime Minister had just begun speaking to around 200 volunteers in east London yesterday when the protester stepped forward.

He told the man who tried to interrupt him, "Don't spoil it".
