Well, that's the main challenge. And neither the Isle of Man nor Gibraltar (nor the Channel Islands, nor Malta, nor any of the British Imperial colonies) count, because they were never formally part of the UKGBI. When it comes to English fragmentation... How about Cornwall? They've had their own nationalist movement going for long enough, firmly backed by the Welsh and the Celtic League. And Yorkshire nationalism's also been gaining a fair bit of ground recently. How about if they both broke away from England?I'm not sure how you get seven new nations out of a Balkanised UKGBI full stop.
Now, five, I can see (England, Scotland, Wales, Northern Ireland, Southern Ireland), but you have to split England into pieces, which is hard. I could, maybe, see seven de facto nations, if there is a multi-sided civil war for some reason, or multiple warlord states following WWIII.
