Context: William Peter (Bill) Barry (30 June 1899 – 21 December 1972) was a Member of the Victorian Legislative Assembly for the Electoral district of Carlton from July 1932 until April 1955.  Barry was a member of the Australian Labor Party until March 1955, when he was expelled from the party as part of the Australian Labor Party split of 1955.  He became, with Les Coleman in the Victorian Legislative Council, joint leader of the Australian Labor Party (Anti-Communist), a party that in 1957 became the Democratic Labor Party. Robert Douglas Gorman (1 May 1898 – 2 November 1970) was an Australian politician and a member of the New South Wales Legislative Assembly between 1933 and 1950.  During his parliamentary career he was, at various times a member of the Australian Labor Party,the Australian Labor Party (NSW) and the Australian Labor Party (Non-Communist) . Arthur Tonge (18 December 1887 – 1 June 1963) was an Australian politician and a member of the New South Wales Legislative Assembly between 1926 and 1932 and from 1935 to 1962.  He was variously a member of the Australian Labor Party (ALP), the Australian Labor Party (NSW) and the Australian Labor Party (Non-Communist) Patrick Leslie "Les" Coleman (21 January 1895 – 6 October 1974), Australian politician, was a member of the Victorian Legislative Council for Melbourne West Province representing the Australian Labor Party from October 1943 until March 1955.  He was a member of the Catholic Social Studies Movement ("The Movement") in Victoria, and was expelled from the ministry and the ALP as part of the Australian Labor Party split of 1955.  After his expulsion from the ALP in March 1955, he became, with Bill Barry in the Victorian Legislative Assembly, the parliamentary leader of the Australian Labor Party (Anti-Communist), which was briefly referred to in the media as the Coleman-Barry Labor Party.  He was a member of that party only until June 1955. Leon William Kennedy Bignell (born 1966), Australian politician, is the member for Mawson representing the South Australian Branch of the Australian Labor Party since the 2006 election. 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. William Joseph "Bill" Denny, {'1': ", '2': ", '3': ", '4': "} (6 December 1872 – 2 May 1946) was a South Australian journalist, lawyer, politician and decorated soldier who held the South Australian House of Assembly seats of West Adelaide from 1900 to 1902 and then Adelaide from 1902 to 1905 and again from 1906 to 1933.  After an unsuccessful candidacy as a United Labor Party (ULP) member in 1899, he was elected as an "independent liberal" in a by-election in 1900.  He was re-elected in 1902, but defeated in 1905.  The following year, he was elected as a ULP candidate, and retained his seat for that party (the Australian Labor Party from 1917) until 1931.  Along with the rest of the cabinet, he was ejected from the Australian Labor Party in 1931, and was a member of the Parliamentary Labor Party until his electoral defeat at the hands of a Lang Labor Party candidate in 1933. Francis Raymond Scully (27 January 1920 – 12 August 2015), Australian politician, from 1949 was a member of the Victorian Legislative Assembly for the electoral district of Richmond representing the Australian Labor Party to March 1955.
