Senator WONG (South Australia—Leader of the Opposition in the Senate) (14:03): Mr President, I ask a further supplementary question. I again invite the Leader of the Government in the Senate to respond on the question as to when the Prime Minister became aware that the conduct of Senator Sinodinos was the subject of two ICAC investigations? I also ask: given that the Wall Street Journal yesterday was told by the former Assistant Treasurer that he would 'soldier on' rather than stand aside, can the minister advise what new information was disclosed to the Prime Minister that resulted in the Assistant Treasurer vacating the front bench?
