Would it not be right to think about my hon. Friend’s proposal in new clause 4 as an attempt to learn the lessons as we go along? It is not as though this is a project without review or evaluation. Already it has oversight from the Department for Transport, the Treasury, the Cabinet Office and the Infrastructure and Projects Authority, and it is subject to National Audit Office review. It is hardly as though people are completely deprived of information. What we need to do is pull together that information and learn clear lessons as we proceed.
