Sorry for the slow response, I've been busy for a couple of days.

On the issue of Northern Ireland, following the Brexit vote there were negligible mutterings about Irish reunification since Northern Ireland voted to remain in the EU. However, such mutterings came from figures such as Gerry Adams and Martin McGuinness, both high ranking figures in Sinn Fein which was the political branch of the provisional IRA.

On the issue of Scotland, the nationalists overestimate the strength of their position in Scotland. The Scottish National Party (SNP) actually lost seats in the Scottish elections back in May and no longer have a majority in the Scottish Parliament so lead a minority government. They are disliked as much as Westminster in the outer regions of Scotland and as much as they may want a second referendum, the governing Conservative Party of the UK will be in no way inclined to give them one considering Scottish independence was rejected less than two years ago by the Scottish people.

Practicalities of a second Scottish referendum aside and on my personal view of the SNP, the notion that the Scots should be granted independence on the basis that they voted to remain in the EU is an easily refuted one. Firstly, both Brighton and London overwhelmingly voted to remain in the EU but nobody is proposing they become independent city states. Secondly, the Scots voted to remain part of the union that is the United Kingdom and that means that when we go to the polls we do not vote as separate countries but as one people, especially in referendums where we do not vote along constituency lines. If Scottish votes had ended up keeping the UK in the EU, you would not find eurosceptic Conservatives arguing for the dismissal of Scottish votes or the expulsion of the country from the UK.
