To the surprise of many, former Labor leader Mark Latham announced he was joining One Nation in November 2018.

Mr Latham is now One Nation’s NSW leader and will contest a seat in the Upper House in the state election on March 23.

Pauline Hanson tells Hayes he is a welcome addition to her party, describing him as the "male version" of her.

And while many say their pairing is doomed, Ms Hanson and Mr Latham think they're a perfect match.

"We're outspoken, we try to speak the truth," Mr Latham tells Hayes.

"We say things that the lefties in particular don't like and we cop all the outrage."

Outrage is something both Ms Hanson and Mr Latham are familiar with. With political careers spanning across decades, they're no strangers to controversy and have a reputation for finding themselves in trouble.

Mr Latham, former Labor Leader and Opposition leader, found himself in hot water in 2001 following a physical altercation with a taxi driver, when he broke the driver's arm during a dispute over a fare.

And then of course there’s that handshake – the intimidating grip that supposedly lost Mr Latham and Labor the 2004 federal election.

More recently, Ms Hanson courted controversy in the senate when she entered wearing a burqa. It was part of her campaign to have the religious garment banned.

Ms Hanson defends the stunt to Liz Hayes: "I was proving a point".

Mr Latham says his position on banning the burqa is in line with One Nation policy.

"The main thing is Pauline whipped it off quickly, and that's what everyone should do," he said.
