Sorry Jack. I did start to write "English Law", but it had too many letters for the thread title.

I think that insisting that parents are present will limit me to the tinies, or don't 10 -14 yr olds go off and do things on their own any more? (there will be musicians present - not really to cope with Johnny, but available in an emergency).

Years ago I was a Playgroup supervisor. At the beginning it was all very informal, then more rules and regulations came in. All of them very sensible in their way, but it took away the spontineity. And you wonder if the abuses that should be caught slip through while the people who were doing it right panic about inspection etc.

But I do think that if there are laws they should be easy to find, and these aren't.
