China and I were both members of the swp at about the same time, we left at different times over different reasons. A heck of a lot of this story I think is directly related to China's and mine experience of the Party and his disillusionment with it. Charles' expulsion mirrors China's, he suddenly found his subs hadn't been received and he was therefore no longer a member. The completely non addressing of sexism, the groups non engagement with the apparent object of their interest all are satirical barbs aimed at the SWP.
