Harold Edward Holt, {'1': ", '2': ", '3': ", '4': "} ( ; 5 August 190817 December 1967), was an Australian politician and the 17th Prime Minister of Australia from 1966 to 1967.
 He was born in Stanmore, New South Wales and won a scholarship to study law at the University of Melbourne.
 Holt went into business as a solicitor, during which time he joined the United Australia Party (UAP).
 In 1935, aged just 27, he was elected to parliament for Fawkner.
 He held this seat until 1949, when he transferred to Higgins.

The Western Australian Liberal Party was a political party which existed from 1911 until 1917 in the Australian state of Western Australia.
 The Party, which had its roots in various earlier political movements, came together in the period immediately prior to the 1911 state election under the guidance of Sir John Forrest, the Federal member for Swan and former Premier of Western Australia, and other leading political figures in the State.
 It was assembled in response to the solid organisation of the Labor Party and had the aim of assisting Ministerial members in winning seats and retaining power in the Western Australian Legislative Assembly.
 The Party did not involve itself in Federal politics, although many of its members were also associated with the Commonwealth Liberal Party and assisted Liberal candidates and members from Western Australia in that capacity.
 The massive defeat of the Ministerial faction by Labor in that election resulted in what remained of the faction formally joining the Liberal Party, which became the first organised non-Labor movement in the State and was a precursor to the Nationalist Party and, later, the modern Liberal Party of Australia (Western Australian Division).
Federal elections were held in Australia on 25 October 1969.
 All 125 seats in the House of Representatives were up for election.
 The incumbent Liberal Party of Australia led by Prime Minister of Australia John Gorton with coalition partner the Country Party led by John McEwen (who had also served as Prime Minister for three weeks after Harold Holt's disappearance) defeated the Australian Labor Party led by Gough Whitlam.
 Even though Labor lost, the election was seen as a good result for the party as it made significant gains against the Coalition.
