European Union Bill

I wonder if there is a special case in this. Some of us approach this question from the hypothetical case that in a few years we might join the euro when it has parity with the pound. It might be relevant to the referendum that people might think, ““If you can’t beat them, join them. It’s been around a long time—you might as well join””. Frankly, that is the way referendum decisions are probably made—in the pub. We are talking about making something quite technical into a demotic sort of fact. Might the discussion in the press get a debate going? Something like the new clause proposed by the noble Lord, Lord Kerr, might be relevant, maybe with some adjustment, to the idea that we need to have the proposition about parity with the euro as part of the question. Could somebody enlighten me as to how that scenario—it is probable rather than possible; it has some common sense about it—would fit with this Bill and with the amendment?
