I hear gasps from the back. It is exactly the same argument. The argument by CND was that if we gave up our nuclear weapons, everyone else would follow suit. That is the argument that was put. The argument put now is that if we enshrine 0.7% in law, all these other recalcitrant countries will follow our example. Interestingly, many former Treasury Ministers and Chancellors of the Exchequer have put their name to this, as have people who have taken evidence. The argument is that those fears that have been expressed are misguided and that none of the disadvantages we have pointed to will come about. Let us test it. If, after five years, we find that those of us who have been a bit concerned were wrong, the Bill can be enshrined again. Indeed, if those who have argued for the Bill are right, it will no longer be a matter of controversy and we will not need a Bill which says that the Secretary of State has to tell Parliament why these proposals fail to meet the target, and that will be the end of the matter. Perhaps we might need a Bill that has a proper penalty and creates a legally enforceable duty on the Secretary of State, which is how this Bill has been sold erroneously to the public, as we have discovered this afternoon.
I believe that the sunset clause is a way to unite us all, end the division over this and give the proponents of the Bill an opportunity to show that their arguments are valid. I have to say that I have my doubts. I beg to move.
