Dr Julian Lewis: Was it not a piece of barefaced cheek for the hon. Member for Leyton and Wanstead (Mr Cohen) to point the finger of accusation at the United States in relation to treaties banning biological weapons? The United States, like this country, signed the treaty to ban biological weapons in 1972, and President Yeltsin admitted in 1992 that for 20 years – as we in the west had suspected – the Soviet Union had been flagrantly breaching the treaty. If accusations of that kind are to be made, should not the hon. Gentleman direct them at the Russians, who, even now, have not cleaned up their act in this respect?
