Embattled Liberal senator David Van is under pressure to resign from parliament following further allegations of misconduct against female colleagues. The Liberal Party on Friday afternoon took action to suspend all organisational resources and support from the Victorian senator. "There will be an urgent meeting this weekend of the party's Victorian administrative committee to further consider the allegations raised," a party spokesman told AAP. Independent senator Lidia Thorpe on Wednesday, under parliamentary privilege, accused Senator Van of harassment and sexual assault, allegations he strongly denied. The following day, former Liberal senator Amanda Stoker accused Senator Van of inappropriately touching her in 2020. Senator Van has said he has no recollection of the incident and he would never have acted inappropriately towards his then-colleague. Opposition Leader Peter Dutton said he had raised an additional allegation with Senator Van in making the decision to expel the Victorian from sitting in the Liberal party room in Canberra. "It's in everyone's best interest that he resign from the parliament, and I hope he's able to do that sooner than later and seek the help that he needs," the Liberal leader told Sydney radio 2GB on Friday. Mr Dutton said he had spoken with Victorian Liberal president Greg Mirabella, as the issue of membership was for the state division to resolve. Earlier on Friday, Mr Dutton said the alleged behaviour was unacceptable. "The thought of sexual assault against any woman in the workplace is not something that I would tolerate," he told Nine's Today program, adding he has referred the matter to the independent workplace authority for investigation. Senator Van said he was "utterly shattered" by the events of the past few days and stunned his reputation could be "so wantonly savaged without due process or accountability". "I will fully co-operate with whatever process Mr Dutton proposes to determine these matters as quickly and fairly as possible," he said in a statement. "While I understand the public interest is high, I will not be making any more public statements on the allegations until a proper examination of these claims is concluded." Ms Stoker said Senator Van inappropriately touched her at an informal social gathering at a parliamentary office in November 2020. Senator Thorpe said the past two days had been horrible and parliament was not a safe workplace for women. "I've never experienced such a toxic workplace culture towards women," she told ABC Radio. "I had a media pile-on that day and it wasn't until a white woman stood up and said 'yeah, this happened to me too' that the media took notice." Senator Thorpe said the case exemplified why women did not speak out against improper behaviour. "I was not believed. I was questioned. I was absolutely demonised that day, by everybody," she said. Assistant Minister Jenny McAllister refused to weigh in on whether Senator Van should resign, but said these were matters for the Liberal Party. Greens women spokeswoman Larissa Waters said Senator Van's position as a parliamentarian remained "untenable" but warned it would not "fix the toxic culture that persists in this building". Ms Stoker called for greater accountability when it comes to inappropriate behaviour in the workplace. "I'm fine, it takes a lot more than this to get to me," she said while filling in for Sky News host Peta Credlin on Friday night. "But I would say this stuff has to stop, parliament is a workplace and it's one that our daughters and sons should aspire to serve in. "We should honour that by our conduct, it's not OK in any workplace." Australian Associated Press
