To some extent, the hon. Gentleman's argument is logical. I am particularly thinking about habitat restoration projects, in which a function may be delegated to carry out such work. There is such a project of heathland restoration ongoing in my constituency. It is a long-term project to restore the historical heathland to the Purbeck area of Dorset. Cancellation decisions would have to be made as a last resort, because if agreements had been made on the basis of the long-term investment required for such a project, one would have to take seriously the losses that might be incurred and, one would assume, any compensation that might be required.
