Yes, I can confirm to my noble friend that, to maintain the credibility of the deterrent and the minimum destructive power needed to guarantee that it does remain credible and effective against a whole range of state nuclear threats from any direction, an assessment has been made. The UK will move to an overall nuclear weapons stockpile of no more than 260 warheads—an increase of 15% from the previous ceiling of 225. I make it clear this is neither a target nor the current number of warheads, but it represents the upper limit of what we think we might need to maintain the credibility of the deterrent.
