Outspoken Liberal backbencher Wilson Tuckey was encouraged that the Opposition Leader had issued a ''definitive statement''.

Mr Turnbull warned yesterday the Coalition would still vote against the Bill if the Government ''ignored these legitimate concerns and insists on a vote on its ETS in its current form''.
