 The UAP leadership ballot was held on 18 April and won by Robert Menzies, who replaced Page as prime minister on 26 April.According to Laurie Fitzhardinge, Lyons' death "removed the only force that had held in check the smouldering animosities and barely suppressed rivalries which divided [the UAP's] members".On 28 April 1915, Lyons married Enid Burnell, the daughter of a family friend; she was almost 18 years his junior.
