Jeremy Corbyn, UK's opposition Labour party leader, has called to scrap Britain's independent nuclear deterrent programme, Trident, angering many within his own party and prompting critics to question the effect it would have on the country's national security.
In this web extra, Hans Blix, the former head of the International Atomic Energy Agency (IAEA) supports Corbyn's call, saying Trident is "a tremendous cost and very little gain".
The former IAEA chief also says he does not think it adds to British security. "I think it's more a question of sentimental status seeking," Blix says, "They will keep their seat in the Security Council even if they do not continue Trident."
