Senator WONG (South Australia—Leader of the Opposition in the Senate) (14:03): I refer to reports that even the Minister for Home Affairs has gone cool on the Turnbull government's business handout. I ask the minister: when did Mr Dutton first advise him that he was leaving the minister in the lurch on the Enterprise Tax Plan? If Mr Turnbull can't even rely on cabinet ministers like Mr Pyne and Mr Dutton to defend his Enterprise Tax Plan, how can he expect this parliament to vote for it?
