(it is, however, set in a vastly butterflied world based on the Germans winning World War One - but the British side of the TL is an attempt at realism through speculation, with some allowances for Rule of Cool).
I'd also like to point out rast's TL, A Shift In Priorities, where the Central Powers win WWI, and over the next few years the British become Socialist (as does Germany). Churchill currently is trying drum up support for overthrowing the British government. It is probably the most detailed TLs I have read on this board.
If there were socialists riots up to the elections causing some minor-moderate chaos
Would Canada declare independence and is it possible that Churchill would move and become the PM of Canada
