Trident

I know that I am going to get one shot at this, and I thank the hon. Gentleman for his great courtesy. I would like to remind him that there was a parliamentary debate and a vote in, I think, the spring of 2007. It is not as if Parliament has not had one vote on the matter, and it will have another one. Does he agree that the cost overrun for the Astute class submarine was so great because of the gap that had been allowed to develop between the completion of the nuclear deterrent submarines of the Vanguard class and the initiation of the Astute class? By ensuring that the next generation of boats follow closely on from the Astute class, any such increase should be avoidable. There is precedent for that, because both Polaris and Trident came in on time and on budget.
