Leanne Castley stepped down as ACT opposition leader less than two weeks after suspending two Liberals from the party room for crossing the floor. This move intensified tensions within the opposition.
The dispute began when Ms. Castley suspended her predecessor, Elizabeth Lee, and Peter Cain from the Canberra Liberals party room.
These events unfolded over 13 days, leading to growing unrest within the party.
Ms. Castley and her deputy, Jeremy Hanson, announced their resignations to allow the party a better chance of success in 2028.
"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,"
they said in a joint statement on Monday morning.
"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 holding the position for 375 days, Ms. Castley became the ACT's second-shortest serving opposition leader, only behind Craig Duby, who served for 6.5 hours.
A party room vote to elect a new leadership team is scheduled for Monday.
On October 28, Ms. Castley announced in a brief statement before question time that she had suspended Ms. Lee and Mr. Cain from the party room.
Summary: Leanne Castley’s resignation after internal party suspensions reflects deep divisions in the ACT Liberals as they prepare for new leadership ahead of the 2028 elections.
