Conservatives and Swedish education?

It looks like the Conservatives are thinking of moving towards a type Swedish education system as they are considering letting parents set their own schools up. Local authorities will be allowed to block all moves towards independent schools in their area unless there is a lot of failing schools in the area.

I would rather they allow anyone to set up a school regardless of how other schools were doing in the area. The competition would only boost standards in all schools as the parents would send their children to the best schools and the worst schools would rapidly run out of pupils and would be forced to close.
