Pauline Hanson has lashed out at Australian senator Fraser Anning, labelling him a racist.
The One Nation leader made the comments to The Australian on Wednesday.
She said Anning unfairly targets people based on race. He has called for a ban on all Muslim and "black" immigration to Australia.
"That blacks should be banned - that in itself is a racist comment," she said.
"What he says is extreme, it's unacceptable... you will find people out there who might have that opinion, but it's not my opinion and not something I've ever said or will ever support."

Hanson, who has been labelled racist herself in the past, said she was not a racist as her comments, such as saying Australia was being "swamped by Asians" had been based on facts.
She also said she had an idea for who Anning was emulating though.
"I feel now he has nothing to lose, I think he's trying to be controversial, to be another Pauline Hanson."
Anning denied the claims and said Hanson had "lost her way".
"I would never preference Labor everywhere over a conservative party like mine, nor would I backtrack on Muslim immigration or endorse a Muslim candidate,"he said.
Anning caused controversy in the wake of the Christchurch shootings after he claimed the attack was caused by Muslim immigration.
"Does anyone still dispute the link between Muslim immigration and violence?" he tweeted in the aftermath of the attack.
