David Seymour: Point of order. There may be some confusion. As I understand it, David Parker had taken speech 11. There are 12 calls available. Now, you are correct that the Business Committee does give an indication of calls. However, frequently in this House, a person stands up and takes a call who may not be in order to speak according to the Business Committee's guidance, and you as the Chair have absolute discretion to call somebody. Now, of course, also, you have a role under the Standing Orders to ensure that people are heard and that there is as much debate as possible. If I as a member seek a call that is available in a debate, then it's not clear why you wouldn't call me to facilitate further debate.
