British Elections 1918-1945

[ObserverIE]

Almost every detail has changed, but the basic pattern is much the same. 1935 is a much underrated election.

Big Labour majorities in Harrow East/West & Brent North! Unthinkable even twenty years before.

Is a lot of that not due to demographic change in that part of north-west London and the Tories not being particularly attractive to South Asian voters?

The Tories won every seat in Birmingham in 1935; that wouldn't happen in a comparable scale landslide today. 

Good grief, I hadn't even noticed, that, even though I knew the Midlands urban area as a whole was very historically Conservative. Wow. Surely that had something to do with Neville, Joseph & Austin Chamberlain, or Stanley Baldwin being relatively local?
Another striking feature for me is that the then very industrialsed, mining based constituency corresponding to modern day uber-bourgoise South Staffordshire is slightly Labour during this Tory landslide, when since 1970 it has been, no word of a lie, one of the Conservatives 10 safest seats (they got 51% in 1997 and 57% in 2010)

That's Cannock, and presumably the Labour vote came from there rather than from what is now South Staffordshire.
