Can someone explain a bit more about why Irish people living in Northern Ireland makes this complicated?
I presume any ID system would show residency and citizenship status. So each of those may be relevant or not relevant for any specific reason.
Only UK residents would need to hold them. Presumably if anyone has the right to work in the UK but isn’t living here, then their employer would need to check that right a different way. This wouldn’t be limited to an NI/I issue. There will be UK passport holders who live in France and commute via Eurostar for part of the week who will be entitled to work here.
I presume non-UK residents would be able to voluntarily use the app, but it might not be compulsory.
Are you saying it would not be legal under the Good Friday Agreement to require a non resident to hold a digital ID to verify their right to work in the UK?
Or are you pointing out that some rights in the UK depend on things other than UK residence? That would be true of voting, for example - I seem to remember that UK resident Commonwealth citizens can vote in elections.
it may be that a digital ID would just say, for example/
Right to work Yes/No
Right to vote Yes/No
Right to access certain NHS services free Yes/No
Etc etc.
