The Northern Ireland potentially rejoining The Irish Republic is a bit surprising to me. Does anyone know if there's actually any chance of that happening?
The chance is very low given the amount of unionists, but that won't stop this being used for what its worth to force re-assessments of agreements etc. Expect the Northern Ireland government to be given a slew of new devolved powers etc. over the next few years as concessions to prevent growing calls for it.
What are the odds of violence popping up again?
We've recently had the threat level for that type of violence raised.
Scottish independence is likely - the question is just how firm the polls need to be before the SNP go there again.
