Senator WONG (South Australia—Leader of the Opposition in the Senate) (14:55): Mr President, I ask a supplementary question. It is interesting, isn't it, the lengths to which this man will go to avoid answering that salient question. He took it on notice previously and now he has done so again. The PRESIDENT: The question, Senator Wong. Senator WONG: Has the Prime Minister asked Mr Brough why Mr Brough has changed his story: first telling 60 Minutes he did ask James Ashby to procure copies of the Speaker's diary and then telling the parliament he did not?
