Australia’s most unsuccessful party loses another leader

Australia’s Most Unsuccessful Party Loses Another Leader

The Canberra Liberals, after nearly a quarter-century in opposition, are once again facing a leadership change. Leanne Castley has announced her resignation after a challenging year as party leader.

The Liberals have been out of power since 2001, when former Chief Minister and Senator Gary Humphries lost to Jon Stanhope in the territory elections. Since then, Labor has secured seven consecutive victories in the ACT Assembly.

On Monday, Castley and her deputy Jeremy Hanson confirmed their decision to step down, paving the way for renewal within the party. Current ACT Speaker and former radio host Mark Parton is widely expected to take the leadership.

“To give the Canberra Liberals the best possible chance of success in the 2028 election, we have made the decision to step down from leadership,” the pair said in a joint statement.
“A vote will soon 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.”

After more than two decades in opposition, the Canberra Liberals hope this leadership change will set the stage for a revival before the next election cycle.
