The Olympic legacy has been a failure in getting a generation of children to participate in sport, Dame Tessa Jowell has claimed.

Sport England’s latest figures showed the number of over 16-year-olds taking part in sport each week had fallen from 15.89million in October 2012 to 15.49million in April 2015.

The former Olympics minister made the comments to BBC Radio 4, but did add the regeneration of east London, which was at the heart of the 2012 Games, had been a success.

Dame Tessa, who wants to become Labour’s candidate for Mayor of London, blamed her “wicked and negligent successors” in government.

She was in charge when London was awarded the Games exactly 10 years ago on July 6, 2005.

Speaking on BBC Radio 4's Today programme, she said: “My particular concern is the second legacy promise was to transform a generation of young people through sport.

“Children in school now are playing less sport than they were in 2009. That’s why it is a wasted opportunity.”
