Former ACT opposition leader Leanne Castley has quit the Canberra Liberals and will sit on the crossbench, accusing her old party of allowing a toxic culture and saying she had been threatened with physical violence.
The Liberals' leader, Mark Parton, flatly rejected the party's culture was toxic and Adam Morris, the party's president, said he was shocked to hear the allegations of physical violence, bullying and harassment.
Ms Castley said she would sit on the crossbench for the rest of the term and had not had any conversations with other parties, such as One Nation, about switching allegiances.
