If Labour MPs deny the party and the country a genuine debate, it will reflect disastrously on them. It will do whoever emerges victorious no good, either. Labour has just suffered one of the worst defeats in its history. If the party doesn’t have the good sense to have a meaningful debate now, you might wonder why it doesn’t just pack up. So come on, Labour MPs. Put your future careers aside for party and national interest. Lend Corbyn a nomination, and let a real debate begin.
