The hon. Gentleman must be unaware that his party is now pledged to keep the nuclear deterrent, according to the speeches made by the hon. Member for Clackmannan (Mr. O'Neill). I have made it clear that the cost of running a Trident deterrent will be well below 2 per cent. of the defence budget. I regard that as an economical insurance and the ultimate safeguard against nuclear blackmail. I regard it at present as an important insurance.
