The decision to expand the UK’s nuclear weapons stockpile by 40 per cent was slipped onto page 76 of the government’s Integrated Review of Security, Defence, Development and Foreign Policy in March. The only reason to announce a major strategic decision in such a quiet way is to avoid attention, which is exactly what happened. The UK is now committed to maintaining a larger stock of nuclear warheads than China (according to US estimates) and there has been too little scrutiny of the policy.
