I have already explained the situation that appertains to the amendment. I do not wish to be unkind to the hon. Gentleman, but if, after all these exchanges, he is still not clear about my rationale for the selection of the amendment, I am not sure, frankly, whether I can greatly help him. I think I am right in saying that the reference to 21 days, as I have just been advised from a sedentary position by the Clerk of the House, is a 21-day maximum. When the hon. Gentleman enquires about supremacy—which of the two takes precedence—I simply make the point that that which is governed by statute is a matter of legal fact. Earlier in this series of exchanges, Sir William Cash asked me to confirm his legal understanding, and I did. That seems to me to treat of the point that concerns Kevin Foster.
