Ivan Peter Lewis (1 January 1942 – 26 September 2017) was an Australian politician. Lewis was a member of the South Australian House of Assembly between 1979 and 2006 in the electorates of Hammond, Ridley, Murray-Mallee and Mallee. From 1979 he was in the House as a Liberal member, however he was expelled from the Liberals in 2000. He was re-elected as an independent, serving until 2006. His decision to serve as Speaker of the South Australian House of Assembly for a Labor government resulted in Mike Rann becoming Premier of South Australia from the 2002 election. His death was reported on 28 September 2017 to have been earlier in the week, in Sydney. Party affiliation Lewis was first elected at the 1979 election as a Liberal candidate. He quickly gained a reputation as a maverick, defying the party authorities on many an occasion. In July 2000, the Liberals finally lost patience with Lewis and expelled him, even though it cost them their majority. At the 2002 election, Lewis contested his seat under the banner of the Community Leadership Independence Coalition (CLIC) and was re-elected. Three other CLIC candidates contested seats in the South Australian House of Assembly but failed. During the campaign, Lewis said he would support any government that would commit to a program of parliamentary reform, including Labor. When pressed by The Advertiser, Lewis denied his statement meant he may help Labor form government, saying "You can quote me: That is bullshit. Clear, unequivocal, hot, green, sloppy, fresh bullshit. I'm not into forming government with Labor". Support for Labor At the 2002 election, with 24 seats required for a parliamentary majority, Labor won 23 seats, the Liberals won 20 seats, the SA Nationals won one seat, with three seats won by independents, including that of Lewis. Lewis negotiated with both Liberal leader and incumbent Premier Rob Kerin and Labor opposition leader Mike Rann. Eventually, Lewis agreed to support a Labor minority government on confidence and supply motions while retaining the right to vote on conscience. In return, Lewis became Speaker of the South Australian House of Assembly, Labor agreed to hold a Constitutional Convention, and Lewis gained concessions for his electorate including the phasing out of commercial fishing in the River Murray, prioritising the eradication of the branched broomrape weed, changing water rates for irrigation, fast-tracking a feasibility study for a weir and lock at Wellington, and
