Ralph Desmond Clarke (born 4 October 1951) is a former Australian politician.
 He was an Australian Labor Party member of the South Australian House of Assembly between 1993 and 2002, representing the electorate of Ross Smith.
 He was the deputy leader of the State Parliamentary Labor Party, and thus the deputy opposition leader, until he was deposed in factional infighting.
The Australian Labor Party split of 1916 occurred following severe disagreement within the Australian Labor Party over the issue of proposed World War I conscription in Australia.
 Labor Prime Minister of Australia Billy Hughes had, by 1916, become an enthusiastic supporter of conscription as a means to boost Australia's contribution to the war effort.
 On 30 August 1916, he announced plans for a referendum on the issue (the Australian plebiscite, 1916), and introduced enabling legislation into parliament on 14 September, which passed only with the support of the opposition.
 Six of Hughes' ministers resigned in protest at the move, and the New South Wales state branch of the Labor Party expelled Hughes.
 The referendum saw an intense campaign in which Labor figures vehemently advocated on each side of the argument, although the "no" campaign narrowly won on 14 November.
 In the wake of the referendum defeat, the caucus moved to expel Hughes on 14 November; instead, he and 23 supporters resigned and formed the National Labor Party.
 Frank Tudor was elected leader of the rump party.
 Hughes was recommissioned as Prime Minister, heading a minority government supported by the opposition Commonwealth Liberal Party; the two parties then merged as the Nationalist Party of Australia and won the 1917 federal election.
 The Nationalist Party served as the main conservative party of Australia until 1931, and the split resulted in many early Labor figures ending their careers on the political right.

 Before entering Parliament he was a farmer and teacher.
 He was also a member of University of Adelaide Council 1970–1973.
 He became deputy leader of the SA Liberals, and hence Deputy Leader of the Opposition, in 1975 when David Tonkin successfully challenged Bruce Eastick's leadership.
 As such, he became Deputy Premier when the Liberals won the 1979 state election, also serving as Minister of Mines and Energy, Services and Supply.
 He remained deputy leader when the Liberals went back into opposition in 1982, returning to the backbench in 1989.

This is a list of Deputy Leader of the Liberal Democrats, a political party in the United Kingdom.
 The position of deputy leader has never formally existed in the party constitution, however since the party's foundation, the Liberal Democrat parliamentary group in the House of Commons have usually elected a deputy leader.
 Although often referred to as the deputy leader of the Liberal Democrats, this post is actually only deputy leader of the Liberal Democrat parliamentary group in the House of Commons and not deputy leader of the Liberal Democrats as a whole.
A deputy leader (in Scottish English, sometimes depute leader) in the Westminster system is the second-in-command of a political party, behind the party leader.
 Deputy leaders often become deputy prime minister when their parties are elected to government.
 The deputy leader may take on the role of the leader if the current leader is, for some reason, unable to perform their role as leader.
 For example, the deputy leader often takes the place of the party leader at Question Time sessions in their absence.
 They also often have other responsibilities of party management.
