Tensions have simmered within the opposition following the suspension of two MLAs. Leanne Castley stepped down as ACT opposition leader less than two weeks after suspending her predecessor, Elizabeth Lee, and Peter Cain from the party room for crossing the floor.
Ms Castley and her deputy, Jeremy Hanson, announced their resignations to improve the party's chances for success in 2028. They declared:
"A vote will be held to elect a new leadership team, and neither of us will be contesting any leadership positions. We extend our full support and best wishes to those who will take on these important roles."
"In the spirit of ensuring a genuine fresh start for the new team, we will not be commenting publicly on the circumstances that have led to this decision."
After serving 375 days, Ms Castley is the ACT's second-shortest serving opposition leader, surpassed only by Craig Duby, who held the role for 6.5 hours. The party will hold a vote on Monday to elect new leadership.
On October 28, Ms Castley announced the suspension of Ms Lee and Mr Cain from the Canberra Liberals party room in a brief statement before question time.
Leanne Castley's sudden resignation highlights deep divisions in the party following controversial suspensions, prompting a leadership reshuffle aimed at uniting the Liberals ahead of 2028.
