I strongly suspect that the result of the Batley & Spen By-Election is a message to the Labour Party’s membership to stop fighting each other, and to unite to fight the real enemy - the worst Populist Tory government any of us can remember - and do what they exist for - to represent the interests of ordinary people. We need a Labour Party than can get elected, not a bloody debating society for dogmatists to slug it out with one another over Labour ideology.

IMHO, of course, and YMMV.
