New South Wales parliament has again been rocked by sexual harassment allegations, with a Greens MP now under pressure to resign.

State Greens MP Jenny Leong has used parliamentary privilege to urge her colleague Jeremy Buckingham to step down.

She’s accused Mr Buckingham of acting aggressively towards her on two occasions this year.

She’s also apologised for failing to come out in support of a former Greens staffer, who has accused Mr Buckingham of sexual harassment.

Mr Buckingham is denying the allegations.

New South Wales One Nation leader Mark Latham tells Ben Fordham he thinks this is part of “faction fighting” within the Greens.

“It’s very rare for a member of one party to stand up and say a colleague should resign from the parliament,” he says.

“But that’s what the Greens have done today.

“My understanding is Buckingham has been demoted on their ticket for the March election to an unwinnable position.

“I think this is part of faction fighting inside the Greens, there has been a power struggle between their soft and hard factions.

“I think he’s on his way out of the parliament one way or another.”

The chaos on Macquarie Street wasn’t just isolated to sexual harassment accusations today, with reports National MPs were moving to oust Deputy Premier John Barilaro as leader by spreading cancer rumours.

Mark Latham says state parliament is worse than a “bear pit”.

“It’s a real animal feeding hour at the moment.

“It’d be a lot better in New South Wales politics if they talked about the issues and they talked about policies that matter to people.”
