If that was the case, the bloody conservatives wouldn't be in power! lol
Thing is, unlike the republic of Ireland, the UK never signed up to the open border (Schengen Treaty). So I don't really see the fuss.
I know North n South, travel fairly freely between each other, but that's something THEYVE done and after brexit, can continue to agree to.
Plus, even before the treaty, we had a special agreement with ROI for each of us to be able to freely travel, so again, I don't see the problem.
I feel, it's just MPs causing problems to deliberately break brexit.
THIS IS MY UNDERSTANDING
