Can someone verify this for me. Is this a letter that David Davis has written himself that has been leaked. And it is him/someone in the British Government saying that should NI leave UK and rejoin Ireland then they will be accepted into the EU as part of Ireland? If I have read this correct, can I ask how Davis knows this. Seeing as UK will be out of the EU, how can he have any authority on who the EU will/will not let join?
