yes and yes,theyre both part of the uk but the two dvlas concerned dont talk to each other so in both cases you have the added grief of creating a new record on the mot system so it wont(for instance)add any unexpired mot from one to the other.as an aside if your n.i.vehicle is a diesel prepare for it to fail the smoke test in the uk,they dont bother doing one in n.i. 😯
