The answer to the second part of my right hon. Friend’s question is that there are established systems that can also be used.
The issue of Northern Ireland is incredibly important. It is central to the delivery of a deal on Brexit. One of the first things that I asked to be able to do was visit the border. It is sometimes difficult to get down to the border: there is a certain resistance to allowing Ministers out of Whitehall, or, if they do get into Northern Ireland, allowing them out of Belfast. However, I went down to Newry and insisted—although I think that some people were not too keen—on visiting the border and criss-crossing and talking to people about the issues. I think that that is the responsible thing to do, to understand the problems at least broadly, so that we can develop solutions as much as possible.
