No, I will not give way.
The nature of regimes in a more dangerous world is what we need to consider today. Although we have reduced our arsenal of nuclear weapons by 50% in recent years—the Leader of the Opposition completely ignored the fact that we have reduced our arsenal so considerably—the number of states with nuclear weapons has increased and the number of tactical nuclear weapons in the world is now over 17,000.
On the question of cost, I would just state that all this—the £31 billion over 35 years, plus the contingency—translates to about 0.2% of total Government spending. That will be reduced if we take account of the advantage for the supply chain of developing this suite of replacement submarines.
I will finish by saying that we need to listen to our allies on this issue. We have an agreement with the French—the Lancaster House agreement—and we have a long-standing agreement with the United States. Our nuclear defence is networked into our other allies as well. We need to think about their response to what we are debating as much as about the future generations that we will protect through our decision tonight.
