Nationals MP Barnaby Joyce has apologised for comments urging rallygoers to use ballot papers as bullets, leading to calls for him to resign from the opposition frontbench.
Speaking at a rally against a wind farm on Sunday, Mr Joyce urged attendees to "load that magazine" when voters head to the ballot box, as a protest against Prime Minister Anthony Albanese and Energy Minister Chris Bowen.
"The bullet you have is a little piece of paper, it goes in the magazine called the voting box. It's coming up. Get ready to load that magazine," he said.
"So goodbye Chris ... goodbye Albo."
Mr Albanese has urged for Mr Joyce to resign from the shadow ministry, saying the rhetoric on political violence had no place, particularly after the attempted assassination of former US President Donald Trump.
"Barnaby Joyce should go. This is the sort of language which has no place in any part of Australian society, let alone in public life," he told Sky News on Monday
"To use a gun analogy at a time when the AFP commissioner has warned that there have been over 700 threats or harassments of members of parliament in the last year is just completely unacceptable.
"It is time that this bloke had a good look at himself, but it's also time that (Opposition Leader) Peter Dutton showed a bit of leadership."
Mr Joyce on Monday walked back the comparison.
"The ballot paper is the weapon you have. It shouldn't be a bullet. It should be a ballot paper," he told Seven's Sunrise program.
"I apologise for using that metaphor."
Deputy Liberal leader Sussan Ley said while Mr Joyce was known to use colourful language, she would not have used the comparison to bullets.
"When it comes to promoting social cohesion, everyone in their language and their words should be lifting the debate to what brings people together, not what pushes people apart," she told ABC Radio.
"I'm not going to go that far (to condemn the comments). I'm just saying it's not language I would have used."
