Dissent within the National Party continued to grow, however, with rebel National MPs Marilyn Waring and Mike Minogue causing particular concern to the leadership, threatening National's thin majority in parliament. When, in 1984, Marilyn Waring refused to support Muldoon's policies on visits by nuclear-powered and nuclear-armed ships, Muldoon called a snap election. Muldoon made the television announcement of this election while visibly inebriated, and some believe that he later regretted the decision to "go to the country". National lost the election to Labour under David Lange.
