Waleed Aly and Lisa Wilkinson had a major on-air spat.
The Ten stars got into a tense exchange on Saturday night’s episode of The Project over the topic of controversial politician Pauline Hanson.
Following Pauline's former colleague David Oldfield’s appearance on the program to discuss the One Nation leader's policies, Lisa rather surprisingly decided to defend her.
"You have to admire her tenacity. No matter what you think of her politics, she has a passion for getting her message out there and there is plenty of people who still want to follow her," she said.
A visibly surprised Waleed replied: "I don't know that I do have to admire that."
Lisa then went on to defend her position, saying, "If somebody has the courage of their convictions, because so often we see in politics, politicians who sway with the breeze."
To which Waleed replied: "That is my point. You can admire her ambition. She is ambitious but... is about what she believes in?"
The debate continued as Lisa praised the party leader for her "toughness".
"Given how often she has been knocked over and she keeps getting back up. I admire that," Lisa concluded. An ever-impatient Waleed countered: "A lot of people are tough."
The debate comes after Hanson fired New South Wales senator Brian Burston from her One Nation party a day after accusing him of stabbing her in the back.
