Mr BURKE (Watson—Manager of Opposition Business) (14:52): My question is to the Prime Minister. I refer to the previous answer he gave to me where he asked me to check what was happening in Senate question time. I refer to the fact that in the Senate Senator Nash has stated that all information was given to the Prime Minister's office. In the light of that, when did the Prime Minister or the Prime Minister's office become aware that Senator Nash's chief of staff had a shareholding in the food industry lobbying firm Australian Public Affairs?
