The Nationalists were never a real force in Australian politics again. The party had spent its entire 12-year existence in government, and was ill-prepared for a role in opposition. In 1931, following negotiations with a group of Labor Party defectors led by Joseph Lyons, the Nationalist Party was absorbed into the new United Australia Party. Although the UAP was dominated by former Nationalists, Lyons was chosen as leader rather than Latham. The UAP replaced the Nationalists as the main non-Labor party.
