SPEAKER: Before I call Dr Liz Craig for the next question, I just want to indicate to members, because I saw some disappointment in one quarter of the House, as to the allocation of the timing of supplementary questions then—I refer people to Speakers' rulings 180/5 and 180/6, which indicate, first of all, that no one has a right to a supplementary question at all. But, more importantly, the rulings of Harrison and Wall, not the substantive part but the very first line, or line or two, are that it is the practice to give the member who asked the primary question the first supplementary; actually, it's been my practice to give them the first two, and after that, if other members go for it, I will move around the House. Generally, if members want to have two supplementary questions, I'll give them straight away rather than breaking it up. I just think the flow works a bit better there. But I did feel some evil looks at me at that particular point.
