My Lords, the noble Lord, Lord Purvis, has raised a very relevant point; I appreciate that it is a rather awkward point for the Government. As the noble Lord said, it is not simply about the overlap of law and whether EU or UK law applies, but there is also—this is why this is absolutely relevant to this Bill—an issue about state aids, because subsidies are covered in the protocol. Many people in Northern Ireland are afraid that there will be a reach-back and that a subsidy that affects Northern Ireland businesses, even if it originates in the UK, will make that UK subsidy regime subject to EU state aid law. This is potentially a clash of regimes and is extremely important.
The Government’s view in the protocol has been that they think that the EU state aid regime should apply only to state aid that is given specifically in Northern Ireland and not to state aid that was designed for the rest of the UK, even if it reaches Northern Ireland businesses. That still leaves the very difficult issue of where the borderline is. You could imagine, for example, a scheme whereby the UK Government gave help to a motor plant in the north-east of England, which was manufacturing cars that were then transported to dealers in Northern Ireland, who then sold them on to southern Ireland. That is where the whole issue arises, because of the EU’s fear about the single market being undermined by the back door.
This issue is not going to go away. Somehow, the Government have to find a demarcation between state aids in the UK and state aids in Northern Ireland. As I have just tried to exemplify with the issue of the motor industry and motor cars, it is extremely difficult to draw a hard and fast line. I do not know whether the Minister can say anything about this. This Bill will pass, but regardless of what is finally enshrined in law when it becomes an Act, this issue will remain a very great problem.
