A former opposition leader in the Australian Capital Territory has resigned from the Liberal Party, alleging a toxic culture and threats of violence within the organisation. Leanne Castley, who served as the ACT Liberal leader, announced her departure on Tuesday, stating she would sit as an independent on the crossbench of the ACT Legislative Assembly.
Statement of Resignation
In a statement, Ms Castley expressed her frustration with the party's internal environment. 'I have simply had enough of being part of an organisation with such a toxic culture,' she said. 'In the last 18 months, I have experienced bullying, intimidation, lies, and even a threat of physical assault. I can no longer be part of an organisation which tolerates this conduct.'
Leadership Turmoil
Ms Castley became the ACT opposition leader following the party's defeat in the 2024 election. However, her tenure was marked by internal strife. In November, she stepped down from the leadership after her decision to suspend two fellow Liberals—Peter Cain and her predecessor Elizabeth Lee—from the party room caused significant upheaval. Speaking to ABC Radio, Ms Castley elaborated on the sustained campaign against her. 'It's not one person, it's not one issue, it's been an 18-month campaign,' she said. 'At some point I had to put a line in the sand and say, ok, I'm walking away.'
Party Response
Liberal leader Mark Parton denied that the party harbours a toxic culture but acknowledged that bullying concerns had been addressed. 'I don't condone bullying, intimidation or inappropriate behaviour of any kind,' he told ABC Radio. Despite this, Ms Castley's departure underscores ongoing tensions within the ACT Liberal Party.
