PMQs: Cameron on nuclear deterrent and Corbyn Trident position

David Cameron took a swipe at the stance of the Labour leader over nuclear weapons when questioned by a Tory MP.

Iain Stewart cited Russia and North Korea, and said it was no time to campaign for nuclear disarmament.

The prime minister mentioned the Back To The Future film series - which at one point looked forward to a future on 21 October 2015 - when he spoke of Jeremy Corbyn, claiming Labour backbenchers "say he should get in his Delorean, go back to 1985, and stay there.”
