If I may, President, in relation to your previous point of order, I just wanted to refer you to Odgers'and I do this also so that the opposition can be aware of the position of the government. In relation to the use of supplementary questions, President McClelland made a statement in which he said:

… supplementary questions are appropriate only for the purposes of elucidating information arising from the original question and answer. They are not appropriate for the purpose of introducing additional or new material or proposing a new question, even though such a question might be related to the subject matter of the original question.

Whilst I do note that there have been some changes in standing orders since that time, I would ask you, perhaps subsequent to question time, to consider that.
