Lots of people on Facebook and Twitter are claiming a United Ireland is a solution to the trade problems caused by the NI protocol.
I don't see how.
The cause of the problem is that GB has left the Single Market whilst NI is effectively still in it.
A United Ireland won't change that, it won't make the Irish Sea border go away, there would be the same barriers to trade between a united Ireland (including NI) and GB as there are currently between GB and the continent.
I can't see any trade advantage as there is already free trade between NI and ROI (and the rest of the EU) so no gain there either.
Have I missed something?
