A Jeremy Corbyn Primer

THE Labour Party conference, which begins in Brighton today, promises to be unlike any in its recent history. A serious debate about abandoning the party's committment to Britain's nuclear deterrent will (probably) play out on the conference floor. MPs who, until a couple of weeks ago, sat on the front bench or were even candidates for the leadership will quit Brighton after Monday, before Jeremy Corbyn gives his speech. The chatter in the bars will be less about whether he will be deposed before the next election than when and in what fashion. And at the heart of it all will be a new leader who remains remarkably little-known (Lucy Powell, his new shadow education secretary, accepted her shadow cabinet post having never met him) in the party and without.
