HC Deb 22 April 1980 vol 983 c122W
Mr. Churchill

asked the Secretary of State for Defence whether, in the light of the reference in paragraph 211 of Cmnd. 7826–I to known improvements to Soviet anti-ballistic missile capabilities, Her Majesty's Government have evidence of any breach by the Government of the Union of Soviet Socialist Republics of the anti-ballistic missile agreement.

Mr. Pym

No. Article VII of the treaty between the United States of America and the Union of Soviet Socialist Republics on the limitation of anti-ballistic missile systems permits the modernisation and replacement of ABM systems or their components subject to the provisions of the treaty.
