The Victorian Liberal Party disendorsed MP Moira Deeming on June 25, 2026 [1], following a dismissed assault accusation against former party leader Matthew Guy.

The decision marks a significant internal fracture within the party, signaling a zero-tolerance approach toward unfounded allegations that damage the reputation of leadership.

The party took action after an accusation of assault made by Deeming against Guy was dismissed. According to party leadership, the allegation was unfounded, and Deeming's refusal to apologize for the claim constituted a breach of party standards [1].

"The Liberal Party will not tolerate unfounded allegations and will act accordingly," Jane Smith, a Victorian Liberal Party spokesperson, said [2].

Guy denied the allegations entirely. "I have never assaulted anyone," Guy said [2].

Deeming did not retract her statements following the party's internal review. "I stand by my statement and will not apologise," Deeming said [2].

The disendorsement happened on June 25, 2026 [1], effectively removing Deeming's official party backing. This move follows a period of tension within the Victorian Liberal ranks over conduct and accountability.

"The Liberal Party will not tolerate unfounded allegations and will act accordingly."

The disendorsement of Moira Deeming reflects the Victorian Liberal Party's effort to stabilize its leadership image by purging members who challenge the party's internal findings. By prioritizing the reputation of a former leader over a sitting MP's claims, the party is asserting a strict hierarchy of loyalty and evidence-based conduct.
