Mark Latham

Mark William Latham (; born 28 February 1961) is an Australian politician and media commentator who is a member of the New South Wales Legislative Council. He previously served as the leader of the Australian Labor Party (ALP) and leader of the opposition from December 2003 to January 2005, leading the party to defeat at the 2004 federal election.

He left the ALP in 2017 and joined Pauline Hanson's One Nation in 2018, gaining a seat for that party in the New South Wales Legislative Council at the 2019 New South Wales state election and winning re-election in 2023. Latham was born in Sydney and studied economics at the University of Sydney. He joined the Labor Party at a young age and worked as a research assistant to Gough Whitlam and Bob Carr. He was elected to the Liverpool City Council in 1987 and became mayor in 1991.

Latham entered the House of Representatives by winning the seat of Werriwa at the 1994 Werriwa by-election. He was included in Labor's shadow cabinet after the 1996 federal election, but left the frontbench in 1998 following a dispute with the party leader, Kim Beazley. He returned to the shadow cabinet in 2001, when Simon Crean became leader. Latham became leader of the Labor Party in December 2003, narrowly defeating Beazley in a leadership vote after Crean's resignation.

He was the youngest leader of the party since Chris Watson in 1901. At the 2004 federal election, the ALP lost five seats and reduced its share of the two-party-preferred vote; the incumbent Howard government was re-elected to a fourth term.
