Change of party leader (Colebatch): Beginning of Mitchell's first period in office: 'Colebatch, as a member of the Legislative Council, tried to persuade a Country Party member to resign his [Legislative] Assembly seat in his favour. Neither the Farmers and Settlers' Association executive nor the parliamentary Country Party were prepared to sanction this arrangement. Colebatch then resigned and the National[ist] caucus elected Mitchell as leader', Hughes and Graham, p. 230 (see 'Sources', below); Mitchell became Premier of a majority Nationalist Coalition government; this was the third leader of the Nationalist Coalition government in two years.
For more detail and a description of the political controversies during Colebatch's brief period in office, see Black, p.104 (see 'References', below), and David Black, 'Party Politics in Turmoil, 1911-1924', in C T Stannage (editor), A New History of Western Australia, pp 381-405, at p. 398-400, (Perth: University of Western Australia Press, 1981, ISBN 0855641819).
'During the term of the Mitchell Government the balance of the three coalition parties changed substantially, with the Country Party growing into the largest bloc and eventually comprising a majority of the parliamentary party', Hughes and Graham, p. 231 (see 'Sources', below). For information on tensions within the parliamentary party, see Black pp 104-105 (see 'References', below).
Loss of general election: Following the election in March 1924, the Australian Labor Party won a majority of seats and Mitchell resigned as Premier.
