After Brexit: Uniting Ireland an 'inevitable' question, says Irish Europe Minister

The Republic of Ireland has been particularly closely involved in the Brexit process. It's the United Kingdom's sixth biggest trade partner and the only country with which it shares a land border. As of January 1, the trade border between the two countries effectively moves to the Irish Sea, with Northern Ireland remaining in the EU's Single Market and Customs Union. And that's not the only change as Northern Irish students are told by Dublin that it will pay for them to keep participating in the Erasmus+ student exchange scheme.
