Starmer purges the Corbynites

Keir Starmer is now putting the final touches to this with a last minute purge of pre-existing candidates and MPs who risk frustrating their election campaign. There is an ongoing row about whether Diane Abbott, the former shadow home secretary, will be barred from standing, but who else might join her?  Oscar Edmondson speaks to Katy Balls and James Heale.  Produced by Oscar Edmondson.
