Jeremy Hanson has been dumped as the ACT's deputy opposition leader, in a significant move that followed weeks of tension within the Canberra Liberals.
Mr Hanson was replaced by Leanne Castley, after losing a snap party room vote 5-3 on Monday morning, but has vowed to stay on in the Legislative Assembly.
Opposition Leader Elizabeth Lee announced the change on Monday morning, saying the decision to spill the position of deputy leader had not been taken lightly.
