Trident

Before my hon. Friend the Minister moves on to the question of costs, I want to make a point about the alternative study. In response to the hon. Member for Islington North (Jeremy Corbyn), who has secured this debate, it is presumably reasonable to assume that, at the very least, a list of those alternatives to Trident that were considered and dismissed, as well as a rough idea of the reasons why they were dismissed, will be published even if technical details cannot be released. Does the Minister accept that, when the hon. Gentleman talks about nuclear weapons killing millions of people if ever used, surely the response is that they are being used every day, because their use lies in the prevention of the use of similar weapons against this country and our interests?
