I take it that the hon. Lady never wants to join the single currency, and that that is her position. It is unfortunately not the position of the Conservative party, which on principle would rule out the single currency for one Parliament, but would not do so for ever. Our position on the constitutional issue was set out in full in my 1997 statement. We discussed and examined the issue, which is a factor in the decision. We do not believe that the constitutional issue is an insuperable barrier to joining the single currency if the economic conditions are met and if there is a referendum of the British people. If the hon. Lady is saying that she would never join the single currency, she will have to persuade the Leader of the Opposition.
