Jeremy Buckingham won't quit, plans to contest the March election

NSW Greens MP Jeremy Buckingham will not stand down from Parliament and intends to contest the March election despite calls from the party's federal leader Richard Di Natale to step aside.

Mr Buckingham is resisting calls to resign after his parliamentary colleague, Greens MP for Newtown Jenny Leong delivered an extraordinary statement in Parliament on Tuesday.

Ms Leong told parliament that she wanted Mr Buckingham to resign over allegations he inappropriately touched former Greens staffer, Ella Buckland, in 2011.

Ms Leong said Ms Buckland had shown strength by speaking out about "Jeremy's act of sexual violence" towards her and "subsequent disgusting behaviour".

"It is cause for much disappointment that our response to recent allegations against one of our own MPs has, to date, been completely unsatisfactory," Ms Leong said.

"If he doesn't do this, then I am urging the party to act so that he is no longer a representative or member of the Greens – because we cannot advance our agenda for a more just, more sustainable and more equitable world when so much energy, effort, time, resources and pain has been exhausted trying to manage one man and his unacceptable behaviour."

Ms Buckland complained in April to the party that Mr Buckingham, a Greens upper house MP, had touched her inappropriately in 2011. Mr Buckingham maintains he was cleared of any wrongdoing.

In a statement, Mr Buckingham said: “The allegations raised were investigated by independent workplace investigation specialists Workdynamic – as per NSW Greens policy – earlier this year and there was no finding of any wrongdoing."

He said the investigation concluded: "The Greens NSW resolve this matter with no adverse finding against you with respect to sexual harassment or inappropriate behaviour towards Ms Buckland".

But newly elected MP, Cate Faehrmann – who replaced Greens Senator Mehreen Ms Faruqi in the upper house – said while she did not "know any woman who hasn’t experienced sexism, sexual harassment or sexual violence", it could not be used as a political weapon.

She said she would push for Mr Buckingham to step aside if a new investigation was launched.

"Right now, however, we have a complaint which has been independently investigated, resulting in no adverse finding, being used to bring down a member of Parliament by his opponents within his own party," she wrote in the Herald.

"Once we begin challenging the presumption of innocence we are on a very dangerous path, indeed, and one that has the potential to return us to the bad old days of mob rule."

Ms Leong and Ms Faruqi also issued a joint statement on the issue, saying: "The culture of sexism, sexual harassment and unwanted sexual advances in society in general and in politics in particular must change."

Fellow Greens MP David Shoebridge tweeted on Tuesday: "Deep respect for this statement from Jenny and Mehreen. I don't believe Jeremy Buckingham should remain on the Greens election ticket."

The Greens' MP for Balmain, Jamie Parker, said he supported Ms Leong and Ms Faruqi's statement. Greens upper house MP Justin Field did not want to comment.
