I found this piece from 2014 a fascinating insight into a by election held fifty years earlier which I was completely unaware of until today. A couple of things that took my eye were Malcolm X talking about "coloured people" (it was a phrase that was used like black people is now for the first twenty years of my life at least and some of my life long friends still use it) and the colour bar in a Labour club.
It's a long article, but well worth a read.
