Right now the UK seems to be in a stalemate in regards to the Irish border situation post-Brexit:
- If they don't leave the Single Market, Brexit would be effectively a farce as the UK would be forced to keep their borders open to immigration by EU citizens.
- If they leave the Single Market, they'll have to introduce customs controls at the Irish border, which is problematic for local residents.
- If they instead introduce customs controls between Northern Ireland and the UK, they'll be effectively alienating their citizens living on the Irish isles. And Northern Ireland would then be forced to allow EU citizens to settle there, being a part of the Single Market.
Given this issue, how could the UK possibly afford to leave the EU without risking Irish reunification? Did the government ever propose an alternative solution that would resolve the stalemate?
