Trident

I note what the hon. Gentleman says, but is not the reality that to maintain the deterrent that we have now, we have to send a clear signal to those involved in the industry and in the execution of the work that we have a long-term commitment? If we do not give them that, we will not retain the skills and our capacity. Without that, we can have no future deterrent and we will remain vulnerable to those powers across the world that will continue to develop their nuclear capacity. Unfortunately, because we will not have the knowledge of what they are doing, we will fall even further behind. Is that not an invidious position in which to place this country?
