On a point of order, Mr. Speaker. In reply to my supplementary question — I think it was in order—about the cut in grant to the pharmaceutical department at Heriot-Watt university the Minister said that he would answer my question when he replied to question No. 17. My hon. Friend the Member for Fife, Central (Mr. Hamilton) raised precisely the same supplementary question and the Minister was about to reply when you, ruled that it would not be appropriate for him to do so since the question appeared later on the Order Paper. With great respect, that seems to be a little restrictive because, if pursued to its logical conclusion, we would never again be able to ask a supplementary question on an issue that appeared in a subsequent question. Will you, Mr. Speaker, clarify the position?
