The SPEAKER (15:16): Yesterday I said, as a result of a personal explanation by the Leader of the Opposition, that I would review the tapes. After the Leader of the Opposition made a personal explanation in the House yesterday about a remark that he was alleged by the Prime Minister to have made by interjection earlier in question time, I undertook to review the tape, which I have done. Just before the Prime Minister responded to what he said was an interjection from the Leader of the Opposition, the Leader of the Opposition appears to make some remarks, but those remarks are not audible on the tape. So I am not in a position to adjudicate on this matter on the basis of the material I have reviewed today. However, I am investigating whether it is possible to enhance the sound and hear the words— Opposition members interjecting— The SPEAKER:There will be silence! I am on my feet. Honourable members interjecting— The SPEAKER:There will be silence. I said I am investigating whether it is possible to enhance the sound and hear the remarks that the Leader of the Opposition can be seen to make. I simply make the point to all members that they are accountable for what they say in the House, even by way of interjection, and there are various forms of the House to ensure that members can be held to account.
