Jacinta Allan quits as Victoria's premier days before a caucus spill she said she could have won. Deputy Ben Carroll, who backs a royal commission into Big Build corruption, is now poised to take over unopposed with just months until the November state election.
Imagine the boss of a big team deciding to quit right before a big championship game, even though she thought she could still win, because a long argument over who leads the team would waste too much time. Her helper, Ben Carroll, is now set to take over just months before everyone in the state votes.
Analysis
A Premier Forced Out by the Calendar
Allan's decision to resign was framed by her as a strategic sacrifice rather than a defeat. She told reporters she believed she would have prevailed in a ballot of Labor's parliamentary caucus and rank-and-file members, but argued that a contested leadership fight, which under party rules can run for up to six weeks, would consume resources and time the party cannot spare with the state election roughly four months away. By stepping aside and chairing Tuesday's caucus meeting, Allan cleared the path for Carroll to take the leadership unopposed and spared the party a protracted internal contest on the eve of a campaign. The move also avoided the spectacle of a Labor membership ballot, a process that could have exposed rifts publicly. Her statement that Carroll had her "unqualified support" is an attempt to present the change as orderly, though the 48 hours of turmoil, including MPs telling her she had lost caucus confidence, suggest the transition was anything but smooth.
The Big Build Shadow Over Her Tenure
Allan's premiership was haunted by allegations of criminal conduct tied to the Big Build, the multibillion-dollar transport infrastructure program she oversaw as transport minister before becoming premier. She has apologised for wrongdoing uncovered by authorities but has consistently rejected calls for a royal commission, a stance that, according to the Guardian's reporting, put her at odds with several of her own MPs who believed the issue could not be contained without a fuller inquiry. The environment minister, Enver Erdogan, publicly broke with the premier on Tuesday morning, telling reporters there was "a case for change" and that yes, a royal commission was needed into Big Build construction sites. The corruption cloud combined with persistently poor personal approval ratings and the rising political fortunes of Pauline Hanson's One Nation to erode Allan's standing with her caucus, even as Labor insiders say the formal push only crystallised after parliament rose for the winter break in June.
What Carroll Brings to the Ballot
Carroll is understood to favour the royal commission Allan resisted, and has framed himself as better placed to resolve the long-running pay dispute with public school teachers, sharpen Labor's economic message and back small business. Until very recently he had publicly ruled out challenging Allan, declaring as late as June that he would not move against her, which makes his rapid pivot a notable political turn. Key Allan allies, including energy minister Lily D'Ambrosio, publicly backed the premier, while minister Steve Dimopoulos struck a more neutral tone, saying the party would "sort things out" through its processes. Former health minister Mary-Anne Thomas, who is already retiring at the November poll, refused to support a spill. With no byelection triggered, Victorian voters will not get a direct say on the change of leader before November, leaving Carroll to inherit both a truncated campaign window and a corruption narrative that now, with his backing for a royal commission, looks likely to dominate the contest.
Key points
- Jacinta Allan announced her resignation as Victorian premier on Tuesday, ending a turbulent 48 hours for state Labor.
- Deputy premier Ben Carroll, who backs a royal commission into Big Build corruption, is set to become leader unopposed at Tuesday's caucus meeting.
- Allan said she believed she would have won a leadership ballot but stepped aside to avoid a six-week contest so close to the November state election.
- Poor personal approval ratings, rising One Nation support and fallout from Big Build corruption allegations eroded Allan's standing with caucus.
- Several of Allan's own ministers publicly broke with her, with environment minister Enver Erdogan calling for a royal commission she had resisted.
An orderly transition could let Labor present a united front and reset its campaign message ahead of the November election. Carroll's openness to a royal commission into the Big Build may also allow the party to draw a clearer line under the corruption allegations that have dogged Allan's leadership.
The change of leader so close to polling day leaves Carroll with little time to establish himself with voters, while the unresolved Big Build corruption issue now looks set to dominate the campaign. Internal Labor disunity, exposed by the public resignations and counter-statements of ministers, could also be exploited by One Nation and the Liberal opposition.
