The parliamentary party operates according to its own rules, unless it is incompatible with the party`s federal constitution. It has the right, if necessary, to defend political positions other than the Bundesrat or the Conference, with the Federal President explaining the reasons to the Federal Steering Committee. It also has the right to decide whether or not to enter into a coalition agreement after consultation with the federal steering committee. The combination of national interest and equal services to the rural population was formulated in this way by John McEwen, federal leader from 1958 to 1971, in 1968: the origins of the coalition date back to the 1922 general election, when the Nationalist Party, the main non-labour bourgeois party of the time, lost the absolute majority it had held since its founding in 1917. The nationalists were only able to stay in office with the support of the two-year-old country party. It soon became clear that a confidence and supply agreement would not be enough to keep the nationalists in office. The Liberals and Nationals reached a coalition agreement in 1990. They fought and won the 1992 and 1996 elections under the leadership of Jeff Kennett. Although the Liberals won enough seats to govern alone, Kennett retained the Nationals in his government. When Peter Ryan became president of the Nationals shortly after the Kennett government`s election defeat in 1999, he terminated the coalition agreement and led the Nationals separated from the Liberals in the 2002 and 2006 elections.
 However, the coalition agreement was renewed in 2008 and the Victorian Liberal and National Parties entered the 2010 elections as a coalition.  The coalition won the 2010 elections with a head start under Ted Baillieu, who resigned in 2013 and was replaced by Denis Napthine. The coalition lost power in the 2014 elections. The coalition agreement was maintained while both parties were in opposition. The Country Party was the coalition`s strongest partner between the 1933 regional elections and the 1947 regional elections, although the coalition did not form a government at that time. Western Australia has never had a Country/National Party Prime Minister.
