On a point of order, Madam Deputy Speaker. May I seek your counsel? My Business and Trade Committee now has oversight of arms control, and is stepping up to its duty by holding tomorrow its first hearing on arms exports to Israel. Some 20 days ago, we requested that Ministers from the Department for Business and Trade and the Foreign Office come and give evidence. They did not reply; they had to be chased last week, and on Friday told us they were not prepared to attend. This is a topic of importance to the House, and it is also important that Ministers, in fulfilling their legal responsibility, are politically accountable. What advice can you give me, at this late stage, to try to ensure that we have Ministers in front of the Select Committee tomorrow morning?
