This is about all EU countries (except the UK) potentially encouraging the idea of Northern Ireland getting what amounts to a free pass to stay in or rejoin the EU (after Brexit) if it returns "home" to the republic. What an imaginative way to achieve what must happen, provided that one is not a rampant NI unionist. On the other hand they may be swayed by the fact that most of them voted to stay in the EU. I'd be curious to know if the historical reasons for the six counties of Northern Ireland wanting to remain in the UK are still valid, or if it has just become a matter of habit. I imagine the Queen wouldn't mind too much if they left.
Great news, particularly for Scotland, as it should make Sturgeon's job of getting independence for us easier and it would make it more difficult for Westminster to say No. Bad news, however, for Gibraltar, as Spain will no doubt try to use the Irish reunification to bolster it's claim. On the other hand, the people of Gibraltar don't want that change, by a huge margin, so one wonders if we are to have another Falklands.
