This is really interesting. According to these figures class division makes little difference on those who vote tory or Labour. The main difference is age with all groups under 50 favouring Labour and those over 50 favouring the tories. Also interesting is that the more educated you are, the more likely you are to vote Labour and also that working people are much more likely to vote Labour, with the retired favouring the tories.
