Australia’s most unsuccessful party loses another leader

Australia’s Most Unsuccessful Party Loses Another Leader

The Canberra Liberals have been in opposition for twenty-four years and have now lost another leader. Leanne Castley announced her resignation after a turbulent year leading the party.

Last year, the Labor party secured its seventh consecutive election win in the ACT Assembly. The Liberals have not been in power since former Chief Minister and Senator Gary Humphries was defeated by Jon Stanhope in the 2001 territory elections.

Leadership Change Announced

On Monday, Canberra Liberals leader Leanne Castley and deputy Jeremy Hanson declared they would step down to allow a new leadership team to take over. Mark Parton, a former radio announcer and current ACT Speaker, is expected to become the new leader.

“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.”

Looking Ahead

The leadership transition aims to revitalize the party ahead of the 2028 election.
Support from outgoing leaders signals a hopeful new chapter for the Canberra Liberals.

Summary: The Canberra Liberals face ongoing challenges after 24 years in opposition, prompting a leadership change to improve their prospects for the 2028 election.
