One could take the view that as I have given the member for Hindmarsh the call we have moved on. But I will do the leader the courtesy of, firstly, pointing out that it is not a ruling, because supplementary questions are at the discretion of the Speaker, and, secondly, that supplementary questions are to arise out of the answer. It is my view that the supplementary question sought to be asked by the honourable Manager of Opposition Business did not sufficiently arise out of the answer the Prime Minister gave. The honourable member for Hindmarsh has the call.
