I support the amendment of the noble Lord, Lord Hain, and that of the noble Lord, Lord Browne, to which I have added my name. I do not need to say very much in support of the amendment of the noble Lord, Lord Hain, because he introduced it so clearly and fully, except to say that I agree with the noble Baroness, Lady Doocey: I cannot see any reason why the Government cannot accept the amendment of the noble Lord, Lord Hain, tonight. It seems to me that it sets out very clearly the commitments made by the UK Government, which we all agree are very important. In its second paragraph, it provides for the possibility that there might be something in the magic solutions to the border. If there were, that would be taken into account in the wording of the amendment of the noble Lord, Lord Hain. I therefore hope that the Government will accept it.
Turning to the amendment of the noble Lord, Lord Browne, my only point is that the extraordinary linguistic fudge in December is very hard for the lawyers to construe. It has been construed by the Commission lawyers in the 118-page draft withdrawal treaty, which was published on 28 February. It has been construed as requiring “a common regulatory area” in Northern Ireland and including Northern Ireland in the EU’s customs territory. Many in London have denounced these solutions; many in London and some in Northern Ireland find them unacceptable. However, they have at least tried; they have produced a draft treaty with draft clauses explaining how they think that fudge could be construed and turned into treaty language. We have not done so: all we have done is make another speech, including the same two suggestions that were made last summer, one of which the Secretary of State for Exiting the EU immediately dismissed the day after as blue-skies thinking. We still seem to be at the stage of blue-skies thinking, but next week in the European Council, we will be confronted by a draft treaty that provides a solution acceptable to some in this country but not acceptable, perhaps, to all in this country. It is half way there. I really worry that if we stick to speeches and do not produce drafts, it is very hard to see how this negotiation will reach a conclusion.
I very much support the amendment of the noble Lord, Lord Browne, and it is in the spirit of that amendment that the Government should be thinking very hard of producing the legal language that they want, and then a real negotiation could start in Brussels. Personally, I do not think that it is possible to find the legal language that matches the Mansion House speech. I believe that the only solution that is likely to be acceptable to all parties in Ireland and in this country is continuing membership of a customs union for the United Kingdom as a whole, which is, of course, what the CBI, the TUC and manufacturing industry want, and we all want for other reasons as well. We do not all want it, but on my side, we do all want it. I think that that is where it will end up. But if the Government think there is another way to go, they really need to produce the language and put it on the table in Brussels quickly.
