The border between Ireland and Northern Ireland has 275 crossings. If there is to be some sort of control, will it be at each and every one of those crossings? Presumably not; otherwise, the number of people that HMRC is going to have to recruit would be much greater than the 3,000 to 5,000 it already needs.
