Precisely the same argument could be applied to the second of the amendments we made last week. The House did not buy the argument last week and the noble Lord, Lord Cormack, was good enough to say today that, in his view, both the amendments laid last week were improvements to the Bill and did not impair it. If we are passing a Bill on this referendum it is very important that we do not pass a defective Bill that omits important elements. Nobody in this House has proposed an amendment to Clause 1(1), which says that there shall be a referendum. In my view, this House is trying to do its job and get right the conditions and rules for that referendum, which is a point that we will need to come back to and which has been raised by several noble Lords this morning. We will have to come back to how the referendum will be conducted and—the point I am concerned about, for reasons well explained in the first leader in this morning’s Financial Times—the timing of the referendum.
I believe that the crucial thing about the assessment called for by the noble Lord, Lord Turnbull—who is completely right—is that it would have to be authoritative.
It would be wholly irresponsible to produce for the country a prospectus based on conjecture. If the country chose to leave the tent and found outside a landscape different from the one that it had expected and a climate much colder, the Government who did that would never be forgiven.
I hope all shades of opinion in the House will understand that the amendment from the noble Lord, Lord Turnbull, is precisely in the category that the noble Lord, Lord Cormack, was talking about—amendments that genuinely improve the Bill. In my view—on the Cross Bench one speaks only for oneself—this would be a genuine improvement and I urge the House to support it.
