Question to the Foreign, Commonwealth & Development Office:

To ask the Secretary of State for Foreign and Commonwealth Affairs, with reference to his oral contribution of 5 September 2017, Official Report, column 83, what the basis is for his scepticism about claims that the North Korean nuclear test of 3 September 2017 involved the successful detonation of a hydrogen bomb capable of being delivered on an intercontinental ballistic missile.

​It is the long-standing policy of the Government not to comment on matters relating to intelligence or national security. We should always be sceptical of claims made by this closed and autocratic regime. This test is however yet another reminder of the grave danger that the Democratic People's Republic of Korea poses.
