In South Australia, initially a Liberal and Country Party affiliated party, the Liberal and Country League (LCL), mostly led by Premier of South Australia Tom Playford, was in power from the 1933 election to the 1965 election, though with assistance from an electoral malapportionment, or gerrymander, known as the Playmander. The LCL's Steele Hall governed for one term from the 1968 election to the 1970 election and during this time began the process of dismantling the Playmander. David Tonkin, as leader of the South Australian Division of the Liberal Party of Australia, became Premier at the 1979 election for one term, losing office at the 1982 election. The Liberals returned to power at the 1993 election, led by Premiers Dean Brown, John Olsen and Rob Kerin through two terms, until their defeat at the 2002 election. They have since remained in opposition under a record five Opposition Leaders.
How long was Tom Playford in political power?
