The hon. Gentleman can request attendance. Insofar as he inquires about other recourse open to him, my advice to the hon. Gentleman, who is a resourceful individual, is that he should make the short journey from the Chamber to the Table Office to table questions on this matter. It may be that he will feel inclined to table more than one question. He may table several. He may do so on a repeated basis. There is no prohibition on repetition in the House of Commons.
