Can Keir Starmer control the Labour left?

Keir Starmer has began a 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. Angela Rayner has now weighed in saying she 'sees no reason why Diane Abbott can't stand for Labour'. Could this become a problem for Keir Starmer? James Heale speaks to Fraser Nelson and Paul Goodman. Produced by Natasha Feroze and Oscar Edmondson.
