Rationally, border control between Eire and NI is a two way process - so the method/extent of control of entry into NI from Eire is up to NI/UK, and control for the reverse direction is up to the EU/Eire.......so why the hell are the EU expecting the UK to come up with THE solution?? Obviously, the UK has proposed an 'electronic' system which they say will remove the requirement for a hard border.....but that only covers one half of the problem . The EU have pooh poohed that idea - but it doesn't prevent the UK/NI from implementing it - as it is to satisfy the UK's requirement - even if the EU do not find it sufficiently acceptable for them to use it as a basis for an agreed trade deal - but what form of border control are they proposing, if any, for their side - other than keeping NI in the Customs Union/Single Market., which is clearly unacceptable to the UK.
