I absolutely reassure the hon. Gentleman that we will not be turning the clock back. I think that the London lessons are about collaboration, school leadership and sharing those best practice experiences across schools. The challenge that I want us to discuss is how we can make sure that all schools play a role in doing that, rather than simply setting grammars to one side and saying that they should not play as great a role across the rest of the school system. I think they should, and we want to have that debate and discussion. Fundamentally—I come back to my opening comments—this is about having more good school places for more children. It is about building capacity through better and more places and by sharing best practice, and about improving school leadership by having schools working closely together.
