Angus Taylor has ousted the first female Opposition leader, Sussan Ley.
The Liberal leadership spill took place on Friday morning during a special party room meeting.
It was an emphatic win, with Taylor able to secure a significant majority, 34 votes to 17.
Jane Hume comfortably won the deputy ballot, 30 votes to 20, with one abstention, beating out predecessor Ted O'Brien and Dan Tehan.
Wearing a brave smile, Sussan Ley announced her intention to leave parliament, triggering a by-election in her NSW electorate of Farrer.
"I look forward to stepping away completely and comprehensively from public life, to spend time with my family," she said.
"I want to express gratitude to the Liberal Party that I have belonged to and loved for more than half of my adult life, to the party room that elected me as their leader nine months ago."
After 25 years on Capitol Hill, she said there were "genuinely no hard feelings" as she wished Taylor well. She walked out of the courtyard to applause.
Not all Liberals are happy with the result. Former Liberal senator Hollie Hughes pointed out Taylor's track record of shifting positions on several issues, including renewable energy, net zero and taxation.
"The way that Sussan [Ley] was undermined from day one, if I was Angus I'd be thinking 'well I wonder if I'm going to get the same loyalty or support that I showed to Sussan'," she told ABC Breakfast.
Hume has been vocal about the failures of the Liberal Party since she was demoted to the backbench after the May 2025 election, in part due to her role in developing a policy scrapping working from home for public servants.
After she claimed "Chinese spies" were working for the Labor Party during the 2025 election campaign, the government repeatedly argued the Liberal party didn't support the Australian Chinese community.
'Zero credibility': Chalmers reacts to Taylor's win
Treasurer Jim Chalmers was quick to highlight Taylor opposed Labor's lowering of taxes at last year's federal election.
"Angus Taylor was the most shambolic shadow treasurer in Australia's history and now he's leader of the Liberals," he said in a statement.
"Angus has zero credibility on the economy and neither does the bin fire that is the Coalition."
