House of Commons votes today on whether to renew Trident. @CharlieSeaWolf and former MP @lembitopik discuss

It's an actual nuclear issue for MPs this week. The House of Commons is due to vote today whether to renew the UK's Trident nuclear weapons system. Trident supporters say it provides an "essential deterrent" for the UK's security. But opponents argue that it is unnecessary and the money involved would be much better spent elsewhere.
