Victorian Liberal MP Moira Deeming faces preselection challenge over dismissed assault allegation against Matthew Guy
Consensus Summary
Victorian Liberal MP Moira Deeming is facing a potential end to her political career after alleging that former party leader Matthew Guy assaulted her by putting her in a headlock at a community event in Sunshine on May 23, 2026. Victoria Police dismissed her complaint on June 16, 2026, after reviewing CCTV footage that showed Guy placing his hand on her shoulder or back, contradicting her claim. Despite conceding she misunderstood the 'technical meaning of the term headlock,' Deeming refused to apologize to Guy, leading Liberal Opposition Leader Jess Wilson to request a state executive meeting to consider her preselection for the November 28, 2026, election. The Liberal Party’s state executive, consisting of 18 members, requires a 75% majority to disendorse Deeming, and the party has indicated it will not expel her from the party but will vote on removing her candidacy. Deeming launched a legal challenge against Liberal state president Brian Loughnane to prevent her disendorsement, delaying the executive meeting and setting a trial for July 17, 2026. One Nation leader Pauline Hanson ruled out recruiting Deeming, citing her refusal to apologize. The controversy has further isolated Deeming, who previously sued former leader John Pesutto for defamation and was expelled from the party room in 2023 before being readmitted. The Liberal Party appears determined to cut ties with Deeming ahead of the election, reflecting a broader consensus that her conduct has damaged the party’s reputation.
