The only Labour councillor I would vote for in Lambeth was Rachel Heywood, who had the audacity to go around wilfully representing the views of her constituency. Lambeth Labour quickly did their best to bully, cajole and pressure her into giving up, like the bunch of pathetic twats they are. So, no I won't be voting for Lambeth Labour because the same bunch of shitehawks are still in power. The notion of some sort of Corbyn-esque takeover from within seems pretty unlikely at present.
I will, however, be voting for Rachel if she stands as an independent.
