A leadership spill of the Australian Labor Party (ALP), the official opposition party in the Parliament of Australia, was held on 28 January 2005.[1] The outgoing Opposition Leader, Mark Latham, stood down 13 months after assuming the leadership in December 2003. Kim Beazley was the only contender for the ballot, and was therefore elected unopposed.
Mark Latham became leader in December 2003 after Simon Crean stood down after losing support from his caucus. However, Latham went on to lose the federal election in October 2004.
Latham stayed on as leader after the election until January 18, 2005, when he stood down, citing ill health.
