Rump UK! EM-2 and Ideology

Tore from my post on the VBCW FB group.

After watching "it happened here", SS GB, and am currently reading Dominion. I was thinking of running some Pulp style "Resistance" games in a world were the baddies win the Civil War. The UK stays natural in the war for Europe and sent volunteers to the now stalled German Soviet war.
Now the question is where do all the separatist factions fall under this idea. Did Scotland and Wales gain independence? Are they occupied and still fighting? Does Canada still hold out for the restoration of Albert?
Does Ireland still control the Northern Island?
Should the US and Japan still have a Pacific war separate from the conflicts going on in Europe? with the European Axis nations deciding that a war across the Atlantic is just not worth it, or is Europe and the US in a state of cold war now?
Thinking set in this late 40s early 50s.
Could have early mods, skins,Teddy Boy's and greasers having fist fights in the streets with BUF youth and axillary organizations.

Then those beatniks and rock'in rollers get radicalized and join one of the many anti-BUF factions. So smaller scale insurgency actions in the towns and the cities.
But some locations in the North and West are still under martial law. With flying columns of rebels still acting out. Causing responses from rapid reaction in parachute and early heliborne cordons in the moors and highlands. Lead by a brutalized Soviet front Major, whos actions only inflame the insurgency!
Could also have a not Vietnam style conflict going on in India with young men trying to smuggle themselves to Ireland and then Canada to avoid being called up.
