Hypothetical situations are sometimes the most difficult to manage. As I said, we will not be part of putting in place hard infrastructure on our island on the Border between North and South, nor is that our objective. The Commission, to which the Deputy referred, has been at the forefront of trying to avoid that happening. The challenge it would face would be in dealing with the consequences of a disorderly Brexit scenario for the protection of the integrity of the Single Market, to which it also has a strong commitment. We would then need to have an engagement with the Commission on how we can maintain the commitment we have to the Single Market, while avoiding infrastructure on the Border between North and South.
