My Lords, I regret that I cannot support Amendment 24 in the names of the noble Lord, Lord Stevenson of Balmacara, and the noble Baroness, Lady Bennett of Manor Castle. It would weaken the authority of our negotiators in agreeing the best possible terms in an international trade agreement for the whole United Kingdom.
In an earlier debate, on Amendment 6, my noble friend Lord Lansley explained that although the noble Lord, Lord Purvis of Tweed, maintained that that amendment did not restrict the prerogative powers of the Government, it did in fact do so by placing limits on the prerogative powers to proceed with negotiations. The arrangements in the CRaG Act, together with the further measures that the Government have taken to increase parliamentary involvement, are sufficient.
Noble Lords will be aware that the negotiation and entering into of international treaties are a function of the Executive exercising their prerogative powers and are a reserved matter for the United Kingdom Parliament.
We should also remember that international trade is an exclusive competence of the European Union, and that member states have the power to block ratification only in the case of trade agreements that include matters other than trade matters and which are shared competences. It seems to me that this amendment would further weaken the prerogative powers and would be likely to give rise to arguments about the extent of the devolved competences described and contained in Schedule 1, which could be exploited by a Government with whom we were negotiating a free trade agreement. Can my noble friend confirm that the Government are already taking the views of the devolved Administrations fully into account? Subject to this assurance, I believe that the amendment would create more uncertainty and should not be accepted.
