Four moments of truth — two clear wins, one leap back, one road not taken

Relax. You are under no obligation to read the small print. There is a clause in Europe’s constitution about bringing our economic policies — money and tax — into line with our neighbours’, but it must have got past the Prime Minister, because he has flown to Rome and signed us up for it. In any case, we shall be able to vote on it. In eighteen months or so from now, if he is still with us, he will stage his promised referendum. One other promise of this kind remains outstanding. Before the pound can be submerged in Europe’s single currency, we shall have to vote in favour — but he has never called this referendum, because he has never yet felt confident of winning it. He must be tempted, at least, to take the two of them together, arguing that logic links them, and believing that if he can win one, he can win both.
