My hon. Friend makes a very important point. The Department does not dictate or impose any particular type of school system, such as a two or three-tier system or all-through schools. It is for the local authority to determine what is necessary, based on the local priorities of the area. The minimal disruption that can be caused in all-through schools is certainly a good thing for local authorities to consider. There are only 25 of them, as I said in my original answer, and it is too early to decide whether they can be rolled out across the country, but they certainly have some benefits and challenges and are something that we are considering.
