My Lords, I put my name to this amendment because I believe its purpose to be profoundly important. I do not have much to add to the very persuasive argument of the mover of the amendment, the noble Lord, Lord Turnbull. I merely wish to endorse a lot of what he said and hope that noble Lords will strongly support the amendment.
I am afraid that the amendment, while I support it, is open to two different interpretations. Therefore, I slightly take issue with the noble Lord, Lord Kerr, and stand somewhere between him and the noble Lord, Lord Foulkes, on this one. The amendment refers to,
“an assessment of the United Kingdom’s intended relationship with the European Union in the event of withdrawal”.
I am not sure that you can really make that assessment on purely normative lines. It has to be descriptive as well. If this amendment is addressed not just to Parliament but to the people, we are asking that the people be informed of the Government’s view of that future relationship. There has to be an element of the descriptive in that. That is the line that I have clung to in my support for this amendment.
The Prime Minister has said over and over again—and to the discomfort, to put it mildly, of a substantial number of his Back-Benchers—that he wishes the United Kingdom to stay in the European Union. However, what if the people in an “in or out” referendum
beg to disagree with him? It is inconceivable to me that, with eventual withdrawal a possibility, the people should vote without the benefit of knowing in advance what kind of relationship he would wish the UK to have with the Union that it is leaving. I would have thought that to so inform the electorate was a simple matter of common sense, not to mention courtesy. In other words, does the Prime Minister have a plan B? If he does not, he must construct one and, having done so, the Secretary of State must publish it and lay it before Parliament before making any order under Clause 1(6). That is what the amendment would be calling for.
At the heart of this assessment, or plan B, would presumably be the end product that the Government seek to gain by negotiation—the best terms that they can obtain for access to the single market, to take but one example. Will the Prime Minister opt for the kind of relationship enjoyed by current members of the European Economic Area and EFTA? Will he take the relationships enjoyed by Norway and Switzerland as his model? I use the word “enjoyed” with some hesitancy, since EEA and EFTA members suffer taxation without representation, having to contribute to the EU’s budget without getting any money back, a reality of which the public ought to be made aware before voting. Or will he be aiming for some other kind of association? What kind of associate status would he judge appropriate for one of the largest economies in Europe and, indeed, the world? Whatever his intentions or preferences, in the case of withdrawal they need to be put on the table for all to see and discuss before the referendum is called.
We on this side of the House are not alone in calling for an eventual impact assessment of the actual effects of withdrawal on the British economy and on the rights of British individuals living both within and outside the UK, as well as on EU citizens living here—the noble Lord, Lord Turnbull, referred to that. That assessment could show that things would turn out to be disastrous if a Government who had taken the UK out of the EU had failed before doing so to formulate a proper vision of the intended relationship. That would be inviting our erstwhile partners to do our thinking for us. I strongly support this eminently reasonable and crucial amendment.
