I seek your advice, Mr Speaker, on how I could get clarification of the answer that I received from the Foreign Secretary in the Yemen statement. I said that the senior civil servant in the arms control unit had advised against sales and that Ministers had overturned that. The Foreign Secretary declared that that was not true. The Foreign Secretary and the International Trade Secretary both refused to attend the hearing of the Committees on Arms Export Controls this year and have both said that they will not attend next year. How can we get them to come before the CAEC to answer these questions?
