Jeremy Corbyn's ex-wife has told 5 live why she voted for his rival Owen Smith in the Labour leadership election.

Professor Jane Chapman was the first of Mr Corbyn's three wives and they met while campaigning for the Labour Party and she was elected as a councillor.

She is now a professor of communications and says she doesn't think Jeremy Corbyn comes across well in the media.

"Last time I voted for Jeremy out of personal loyalty," she told 5 live's Emma Barnett. "But I've been so saddened and really upset. It's been such a painful sideshow this last year."
