Nationalist Party of Australia
The Coalition was defeated, even Bruce even lost his own seat. He was succeeded as leader by former Attorney-General John Latham. The Nationalists were never a real force in Australian politics again. Having only ever been in government they were not prepared for a role in opposition.  However in 1931, a group of Labor Party members led by Joseph Lyons, left the ALP to join the conservatives. They formed a new group, the United Australia Party (UAP). Most of the UAP were former Nationalists, but they chose Lyons as leader and Prime Minister  The UAP replaced the Nationalists as the main conservative anti-Labor Party.
