The recent Northern Irish Assembly Elections were significant in all sorts of ways, as this great piece explains. Northern Ireland may be to moving to a very different place politically. Unionism no longer has a majority, the Unionists may no longer hold a veto in the Assembly (via the petition of concern) and there is, on paper at least, an anti-Brexit majority in the new Assembly, that could govern the only part of the UK with a land border with the EU.
