Most Londoners won't see Olympics
A poll suggests nearly two thirds of Londoners don't intend to see an Olympic event in person.
The survey also shows half of people asked don't think the tubes and roads will cope during the games.
It comes as a Heart investigation has discovered there are serious concerns over how prepared London is to help the 35,000 disabled visitors.
