A survey commissioned by London mayor Boris Johnson has revealed more than 84 per cent of young people believe that the 2012 London Olympics will be good for the capital.

The Young Londoners Survey saw 43 per cent believe that the Games will lead to an increase in sports participation, while a further 25 per cent of those questioned expect the event to result in improved leisure activities. Johnson said: "For every cynic, there are thousands of budding Tom Daleys eager to reap the benefits of the Olympic legacy with bigger better sports facilities and a huge sporting momentum.

"I truly believe that if we engage every young person an interest after school, from sports, music and dance to team building groups like the Scouts, we can nurture their ambition and fuel aspiration." The Young Londoners Survey questioned 1,000 teenagers on a range of topics, including the Olympics, crime, transport and culture.
