Mr. Peter Sheridan:

I briefly touched on that in a previous answer. There are two dangers that we foresee with it. If the Border is along the land frontier between the Irish Republic and Northern Ireland, with customs posts and so on, then that certainly runs a risk of semi-detached status for northern nationalists who are aligned more with this jurisdiction than London. Any obstacles or impediments on the Border would make people start to question their ability to be Irish. The Good Friday Agreement allowed people to be British, Irish or both. Likewise, if the Border is in the middle of the Irish Sea or on British ports then there is a risk of semi-detached status for those in the Protestant community who are aligned with London. They may find that in travelling from one part of the UK to another they will have to produce some identity documents. I do not know what the answer to this is. Both communities have very real fears.
