Corporation Tax (Northern Ireland) Bill

I welcome this measure for Northern Ireland, and I think that it will inevitably come to Scotland when we have a large Scottish National party group in Westminster. The argument about the land border is a strange one, because there are many places on land borders that have different rates of corporation tax. Logically, that could lead to a situation in which corporation tax was set island-wide in Dublin. I would not like to see such a situation, but that is the logic of the argument about the land border.
