Nuclear Deterrent

My Lords, does the Minister agree that the only sensible alternatives in this case are the minimum credible nuclear deterrent or no nuclear deterrent at all, not something that falls between the two? Credibility is in the eye of the beholder, so proposed savings around the margins of the nuclear deterrent programme —in themselves, they may be quite large sums but they are necessarily only a small percentage of the total programme—then put at risk the effectiveness of that programme. They do not represent value for money.
