Five years ago this month, the London Olympic Games - seen as a great success for Britain - came to a close.

At the time, the country was promised that the end of the Games would not mean the end of the success story, that there would be a lasting legacy for sport participation.

But, in England at least, that promise was broken.

The government gave Sport England £1bn to invest in grassroots sports, and Jeremy Hunt, then Secretary of State for Culture, Olympics, Media and Sport, said the Games provided an "extraordinary chance" to "reinvigorate this country's sporting habits for both the young and the old".

He described it as a "once-in-a-generation opportunity, a real golden moment for the UK".

But there has been virtually no increase in participation in sport.

Since 2005, when London won the bid to host the Olympics, Sport England has surveyed people about their physical activity.

In 2005-06 the proportion of over-16s in England who played sport for at least 30 minutes each week was 34.6%. By 2015-16, it was 36.1%.

Among 16- to 25-year-olds, there has been no change at all in participation rates since 2005-06.
