Gosh, I could do with time to think about that one as well. It seems an important issue, and I'm not aware of any work in the U.K. that has addressed that point. Clearly, it does raise very important issues.
There has always been an issue, when you're relocating families, of moving young people between schools and of trying to ensure that that process is done with as little disruption as possible. All I can say is I think that would be an important area to explore further.
