What happened to Moira Deeming?
Expulsion from the Liberal Party
- Moira Deeming was expelled from the Victorian Liberal Party in 2023 after attending the Let Women Speak rally on 18 March 2023, where neo-Nazi groups were present (The Guardian)
- The expulsion was moved by John Pesutto as party leader and passed by a secret vote with a narrow margin (The Age)
- Before expulsion, the party room voted to suspend Deeming for nine months in a compromise that ultimately failed (The Age)
Defamation lawsuit against John Pesutto
- Deeming sued Pesutto for defamation, alleging he falsely portrayed her as aligned with neo-Nazis and white supremacists after the rally (ABC News)
- The trial began in the Federal Court in September 2024 (The Guardian)
- Pesutto argued he needed to protect the party from reputational harm, but the court found he had defamed Deeming on five separate occasions (ABC News)
Court ruling and aftermath

- The ruling came two weeks before the leadership spill that ousted Pesutto (Wikipedia)

The implication: a single party-room decision snowballed into a legal and political crisis that defined Pesutto’s tenure.
Why was Moira Deeming expelled from the Liberal Party?
Reasons for expulsion
- Deeming’s attendance at the Let Women Speak rally on 18 March 2023 was seen as breaching party values, given the presence of neo-Nazi groups (The Guardian)
- Pesutto argued publicly that the party needed to distance itself from any association with extremism (ABC News)
Party procedures and vote
- The expulsion motion was moved by Pesutto as party leader (The Age)
- The vote was secret and passed by a narrow margin, though exact figures remain undisclosed (The Age)
- Before expulsion, a compromise to suspend Deeming for nine months was attempted but failed to hold (The Age)
Reactions from party members
- The expulsion split the party, with some MPs supporting Deeming and others backing Pesutto’s stance (SBS News)
- By late 2024, five senior Liberal MPs had signed a petition for a party-room meeting to challenge Pesutto’s leadership (SBS News)
The catch: what was framed as a principled stand became the catalyst for a leadership crisis.
Who is the leader of the opposition in Victoria?
Current leader
- As of late 2024, Brad Battin is the leader of the opposition in Victoria (Wikipedia)
- Battin won the leadership vote on 27 December 2024 after Pesutto’s resignation (Wikipedia)
John Pesutto’s resignation
- Pesutto held the position from 2022 until his resignation in December 2024 (Wikipedia)
- He resigned after losing a leadership spill motion triggered by the defamation case fallout (Wikipedia)
Brad Battin’s leadership
- Brad Battin, the member for Gembrook, succeeded Pesutto as leader of the Victorian Liberal Party (Wikipedia)
- Battin now leads the party into the next state election, facing Premier Jacinta Allan’s Labor government.
What this means: the Victorian Liberal Party enters a new chapter under Battin, but the scars of the Deeming affair remain.
Who is the head of the Liberal Party in Victoria?
Party leadership structure
- The head of the Victorian Liberal Party is its leader, currently Brad Battin (Wikipedia)
- The party also has a state director who manages day-to-day operations, but the leader is the public face and political head.
Role of the state director
- The state director oversees campaign strategy, fundraising, and organisational matters, distinct from the parliamentary leader’s role.
Current head
- Brad Battin is the current leader, having taken over from John Pesutto after the December 2024 spill (Wikipedia)
- Pesutto was the leader from 2022 until December 2024 (Wikipedia)
The trade-off: a new leader may unite the party, but unresolved tensions from the Pesutto era linger.
What is the controversy surrounding Moira Deeming?
Rally attendance
- Moira Deeming attended a women’s rights rally on 18 March 2023 where neo-Nazi groups were present (The Guardian)
- She has stated she did not endorse or associate with those groups, but her presence was enough to trigger party action.
Alleged links to neo-Nazis
- John Pesutto publicly distanced the party from Deeming, implying she supported or was aligned with neo-Nazis and white supremacists (ABC News)
- Deeming claimed this was defamatory and sued for damages (The Guardian)
Pesutto’s comments and defamation
- The Federal Court found Pesutto defamed Deeming on five separate occasions (The Guardian)
- The court ordered $300,000 in damages, a significant financial and reputational blow to Pesutto (The Guardian)
Why this matters: the Deeming affair reshaped Victorian Liberal politics, turning an internal dispute into a national story about party discipline and defamation.
