Thanks very much, all of you. Half the time I want to argue with you, but the other half I want to praise you.
Let me just make one point with Mr. Mitchell and then move on to Mr. Smith.
Mr. Mitchell's point was, if I understand the argument, be careful about using an act of Parliament to establish a machinery of government piece, whether it's a cabinet committee or a central agency, because the challenge is that you're getting into the kitchen, you're limiting flexibility, and you're binding on successors. Is that roughly the caveat?
