Like other senior members of the party, after having no conservative government since Alexander Mair in 1941, Robson had no experience in government, had little interest in policy and alienated many party members by trying to forge a closer alliance with Michael Bruxner's Country Party. Over a year after Robson assumed the leadership, at a party meeting on 20 September 1955, senior party member Ken McCaw moved that the leadership be declared vacant, citing that Robson's leadership lacked the qualities necessary for winning the next election. The motion was carried 15 votes to 5. Morton was then elected unopposed as leader, with Askin remaining as Deputy Leader.
