Defeat in parliament (Wilson): Beginning of Lefroy's period in office: Disagreements within the Wilson Liberal government and between the government and Country Party members of the Assembly were compounded by the split in the Australian Labor Party in 1916 over the introduction conscription to send Australian soldiers to Europe during the First World War. By 1917 this volatile situation had led to a major regrouping of parties and the formation of a Parliamentary Nationalist Party consisting of members of the Liberal Party, the Country Party and 11 defecting Labor Assembly members. Wilson was replaced by Lefroy as the compromise choice as leader of the Parliamentary Nationalist Party; for more detail of these events, see Black, pp 101-103 (see 'References', below). Lefroy became Premier of a majority Nationalist Coalition government.
Hughes and Graham indicate that the Nationalist Coalition ministry was composed of 4 Liberals, 3 members of the Country Party, and 2 members of the National Labor Party (see pp 229-230, in 'Sources', below).
Change of party leader Over the period 1918-1919, the Lefroy government appeared incompetent and to lack cohesion; by April 1919, Lefroy had only the limited support of his party colleagues and he resigned. For more information, see Black, pp 103-104 (see 'References', below).
