Under-fire Labor MP Emma Husar says she will not re-contest her western Sydney seat at the next election.

After weeks of sensational reports that she had allegedly abused and intimidated staff, as well as being sexually inappropriate around them, she announced her decision in a statement on Wednesday.

“This stops now. Enough is enough. I’ve spoken with Bill Shorten and let him know that I won’t be re-contesting the next election,” the statement said.

“I absolutely reject the malicious allegations which have been published to my great detriment.”

Ms Husar holds her seat of Lindsay by a slim margin after narrowly winning it from the Liberals in the 2016 election.

She had earlier labelled the allegations a political ‘stitch up’ by an unhappy former staff member.

Ms Husar is facing two separate investigations by the Labor Party and Parliament’s expenses authority over the allegations.

“Given my reputation has been completely shredded by nameless, faceless people, I see no point in waiting for this report,” Ms Husar’s statement said.

“This vendetta lead to threats to my personal safety, the trolling of my children online and media parked outside my house around the clock.”

Opposition Leader Bill Shorten was asked about her future earlier on Wednesday before she announced her decision.

“I’m not going to provide a running commentary about the matter until the report is concluded,” Mr Shorten told reporters in Sydney.

“The complaints process has been compromised by a number of people talking about it. I won’t make that mistake.”
