There have been some crucial points made there. If there were a second independence referendum in Scotland - I supposed there is no certainty on this - and if Irish voters were to be allowed to vote in it, would that be a matter for the Scottish Parliament or Westminster? Can Mr. Holder be clear on that?

I am curious about the issue of citizens who arrive in Dublin Airport, as Mr. Holder said, and if we were to try to enforce UK legislation. I would be particularly concerned if some of that UK legislation were in breach of European legislation.

I refer to what would happen if the UK decided to change its commitment to the European Convention on Human Rights or something such as that and there were questions raised at a European level. I ask Mr. Holder to tease out that issue.
