The Australian Nationals are facing a fractured leadership contest following the shock resignation of David Littleproud, who declared on March 10 he was "buggered" and had "had enough" after serving as a "human punching bag" in recent months.
Littleproud, the Member for Maranoa, will step down by the end of the week, citing exhaustion after a turbulent period marked by the Coalition's May election defeat and internal disputes over energy policy and hate speech laws.
He leaves a legacy defined by shifting the Coalition toward nuclear energy and leading the successful "No" campaign during the Voice referendum.
The race to succeed him has quickly intensified, with Deputy Leader Kevin Hogan and Senate Leader Bridget McKenzie both confirming their candidacies.
Hogan, who has served as deputy since May, entered the fray after being approached by colleagues, while McKenzie is expected to formally announce her bid on March 11.
They join conservative Senator Matt Canavan, who has already staked his claim on a platform opposing "crazy net zero policies" and excessive government spending.
Former leader Michael McCormack is also widely expected to nominate, further crowding the field.
Liberal Leader Angus Taylor paid tribute to Littleproud as a "man of integrity," while Prime Minister Anthony Albanese acknowledged their mutual respect despite political differences.
As the party prepares for a leadership ballot, the incoming leader will face the immediate challenge of reunifying a splintered party room and navigating the Coalition's path toward the next federal election.
