NI is a two part process though - (1) does NI want to leave the UK and (2) does ROI want to accept NI (they surely don't want to be totally independent). I'm not at all sure ROI would want to or should take in NI - it would be very expensive (they receive something like 7B from the UK annually just to keep themselves going) and troublesome. If we did take NI, it would want to come with a massive dowry from the UK!If Scotland goes then NI looks like an outlier.
