It's a statutory duty but the statute is quiet on exactly how those facilties have to be provided.
You sure? In Sept last year Lord Moynhan, outgoing chairman of the British Olympic Association said,
"We should be looking at changing the law to make provision of sport and recreation opportunity a statutory requirement.
"At the moment in England it's discretionary and once it's discretionary it's inevitable that councillors will be looking for discretionary cutbacks first."
That surprised me, hence the question.
