Lord Lilley: Can my noble and learned friend confirm that, if the Government invoke Article 16 to tackle the problems that they foresee, they would still need legislation like the Internal Market Bill to implement it? Do not we need that legislation on the statute book before the end of the transition period to reassure businesses that they will not have to either submit export declarations or pay tariffs on all goods between Great Britain and Northern Ireland?
Lord Keen of Elie: My Lords, I entirely concur with the observations of my noble friend. As I indicated before, it is one thing for the Executive to determine an issue at the level of international law in terms of a treaty, but they cannot utilise that in order to ignore primary legislation of our domestic Parliament. Therefore, a means has to be in place to address the effect of that domestic legislation, and that is the purpose of Part 5 of the UKIM Bill. It will enable us to bring forward regulations that will do that—and, indeed, regulations that will require explanation and the affirmative approval of this House.
