Nationals Senate Leader Barnaby Joyce says he is frustrated by personal criticism from within the Liberal Party and has threatened to quit the Coalition.
Senator Joyce's strong stance against an emission trading scheme has angered some Liberal Party MPs.
Senator Joyce told Channel Seven his critics should have the courage to state their views in public.
"If after about four years you continually deal with unnamed sources in the paper and those unnamed sources say that the source of all their problems in life is you, then you say if you want to make yourself public and you are at the appropriate level, I'll leave," he said.
