The New Hebrides, now renamed Vanuatu, achieved independence as planned on 30 July 1980 under Prime Minister Walter Lini, with a ceremonial President replacing the Resident Commissioners. The Anglo-French forces withdrew in August, and Lini called in troops from Papua New Guinea, sparking the brief 'Coconut War' against Jimmy Stevens's Vemarana separatists. The PNG forces quickly quelled the Vemarana revolt and Stevens surrendered on 1 September; he was later jailed. Lini remained in office until 1991, running an Anglophone-dominated government and winning both the 1983 and 1987 elections.
