The hon. Gentleman might wish to make a speech himself on the subject in due course, but he is fundamentally wrong. It is absolutely the case that his predecessors from his party recognised the need for evolution, and the need for handling the planning system with care. The planning system does not deliver quickly. Changes to the planning system have an impact over several years. It is probably a period of five to 10 years before their full impact is felt. If one fiddles with that system without thinking about what one is doing and introduces changes that are ill thought-out, they can be hugely disruptive.
