Prime Minister Malcolm Turnbull has called on maverick Queensland MP Bob Katter to apologise and withdraw a campaign video depicting him as a cowboy shooting two men dead.
Mr Katter provoked online anger after releasing the advertisement just days after 50 people were killed in America's worst ever shooting in Orlando, Florida.
He believes the video - which has clocked 100,000 views - is "brilliant" and "screamingly funny".
But Mr Turnbull begs to differ.
"The advertisements were in the worst of taste and Mr Katter should apologise and withdraw them," he told reporters in Sydney on Thursday.
