Dean Craig Brown, AO (born 5 April 1943) was the Premier of South Australia between 14 December 1993 and 28 November 1996, having won the 1993 election landslide, and also served as 10th Deputy Premier of South Australia between 22 October 2001 and 5 March 2002, representing the South Australian Division of the Liberal Party of Australia. John Olsen successfully challenged Brown for the premiership a year prior to the 1997 election but the party was reduced to minority government, though he too would lose the premiership, due to the Motorola affair where he misled parliament, to Rob Kerin, several months before the Liberals lost government at the 2002 election.
