Further to the question from the right hon. and learned Member for North-East Fife (Mr. Campbell), are not the Government in a wobble over the whole position on ballistic missile defence? The Secretary of State's predecessor, Lord Robertson, said: We are not in favour of developing ballistic missile defence systems"—[Official Report, 10 May 1999; Vol. 331, c. 10.], yet we find that the Government have already reached agreement with the United States through their receipt of information and the upgrade of Menwith Hill. We also know that the Secretary of State has had serious discussions with his counterparts in the United States on the upgrade of Filingdales. Is not the reality that they dare not say what their intention is because of their fear of their own Back Benchers, who do not like it?
