[holding answer 29 June 2009]: The UK is committed to the long-term goal of a world without nuclear weapons and is actively working towards creating the conditions to make that goal a reality. We believe that the principal means to achieve this is through the non-proliferation treaty (NPT), resulting in a reinforced sense of shared responsibility for both nuclear and non-nuclear weapons states.
At the moment we believe it would be premature to press for a Nuclear Weapons Convention, which be unlikely to make any headway and would distract attention from efforts to bolster the NPT. We do nonetheless believe there may be a role for a Nuclear Weapons Convention in the future when the time comes to establish a final ban.
