The Border Force row exposes differences between British and Irish citizenship that have to be settled

Leaving aside the delicious irony, I would guess that Sinn Fein are right: the attempt to limit recruitment for the UK Border Force to British passport holders is discriminatory and would be overthrown  in court.  Why should anyone have to produce a passport for a job in Northern Ireland anyway?  This has echoes of the malign Windrush problem. without feeling the  pain – yet,   Up to now only when you go abroad and need to produce a passport has the issue of citizenship arisen ; but it  is not quite as cut and tried as the unionist academic Graham Gudgin writes in the FT.

Brexit will make some sort of change  to citizenship for Northern Ireland people, but exactly what change is far from clear.  The ability of the European Court of Justice to disapply certain categories of UK legislation – only recently recognised in the UK – disappears after Brexit unless it is restored for NI in some form to remain compatible with the GFA legislation.  If not there could be different rights for British and Irish citizens and that would surely be intolerable. What is hardly mentioned is that everybody in NI of whatever citizenship description, retain their full British citizen rights and entitlements  if they move to GB and full Irish rights and entitlements if they move south .

Or so I believe. Perhaps like WIndrush cases, anomalies will be exposed under challenge but this has not happened so far. But Brexit may make  the difference.

The legal situation is pretty recondite but behind it lies  a political issue. If 40 % of the population call themselves Irish citizens, what leverage does that give the Irish government in the affairs of Northern Ireland if citizenship rights are no longer identical? How do citizens assert their  citizenship preferences  without displaying a passport and claiming different rights if rights eligibility diverges?  The Border Force row could become a test case.
