Britain’s main political parties are very diverse coalitions, made up of all kinds of different groups. Like some kind of cruel reality TV show, utterly ill-matched people are forced to work together and pretend to like each other. In a particularly disturbing social experiment conducted every autumn, the members of these sprawling ideological tribes are herded into a specially secured zone in some unfortunate city, with only each other for company. With such a combustible mix of personalities, and a shedload of booze poured on top, it’s a wonder more people aren’t injured.
