Labour MP and leadership hopeful Owen Smith was caught on camera telling the female leader of the Welsh nationalists that she was only invited on TV because of her gender.

The exchange took place just as the former shadow Welsh secretary and Leanne Wood were about to take part in the ITV Wales general election debate in 2015. The footage, which was not broadcast, is embedded below.

Wood asked Smith: "Have you ever done Question Time, Owen?"

"Nope, they keep putting you on instead," Smith replied.

"I think with party balance there'd be other people they'd be putting on instead of you, wouldn't they, rather than me," Wood shot back.

"I think it helps," Smith said, adding: "I think your gender helps."

Wood then gave a withering "yeah" before the video cut.
