Mr. Llew Smith

To ask the Secretary of State for Defence, pursuant to his answer of 23 January 1998,Official Report, column 719, what factors underlay his decision to designate exports of nuclear materials to the United States after 1979 as a matter covered by Category 1 of the Code of Practice on Access to Government Information. [27249]

Mr. Spellar

To disclose details of individual transfers of special nuclear materials between the United States and the United Kingdom, other than aggregated information of transfers during the period covered by the Barter arrangements, could reveal information which both the UK and US regard as classified because, if revealed, it could be of benefit to a potential enemy.
