In 1978, the National Party split from the National Country Party over the coalition question, with the NCP remaining in coalition with the Liberal Party, and the NP occupying the cross-benches. In 1985, the two parties reunited as the National Party of Western Australia, affiliated to the National Party of Australia. However the three former NCP members, unhappy with some of the terms of the reunification, quit the new party and joined the Liberal Party.
