Charles Kingston Liberal Charles Kingston Liberal The 1899 South Australian colonial election was held on 29 April 1899 to elect all 54 seats in the South Australian House of Assembly.

The incumbent liberal government led by Premier of South Australia Charles Kingston in an informal coalition United Labor Party (ULP) led by Lee Batchelor defeated the conservative opposition led by Leader of the Opposition John Downer.

Although the conservatives won more seats, the liberal government retained power until later that year, when new conservative leader Vaiben Louis Solomon forced the government to resign, but only held office for one week.

The liberals held government until the next election through leaders Frederick Holder and John Jenkins.

The 1899 election was a contest between three increasingly dominating groups – the ULP, the conservative National Defence League (NDL) which renamed to the Australasian National League (ANL), and the Kingston liberals.
