Joseph Estrada was last night heading for a crushing victory in the Philippine presidential election. An unofficial nationwide exit poll of 13,491 people showed Mr Estrada with 36 per cent support, more than double of his nearest rival, House Speaker Jose de Venecia. Another unofficial poll had a similar result. 'It's all over bar the counting,' Mr Estrada said. Officials said at least nine people were shot dead and tens of thousands unable to vote after poll officers fled in fear of gunmen. The violence brought to nearly 50 the number of people killed during the campaign and on voting day. Despite the deaths, the Commission on Elections described the day as peaceful. 'The elections of 1998 proceeded without being eventful,' commissioner Teresita Flores said. Violence was concentrated in the south. Suspected supporters of a warlord mayor fired a mortar barrage on Panamao on Jolo island, injuring 11 civilians. In Lanao province on Mindanao, more than 40,000 voters were unable to vote due to gunmen roaming the streets and roadblocks preventing the delivery of ballot boxes. Official results are unlikely for a month but the presidential and vice-presidential winners should be declared within 10 days. The commission and the watchdog National Movement for Free Elections estimated turnout at 80 per cent. The exit poll showed President Fidel Ramos' nominee for the vice-presidency, Gloria Macapagal-Arroyo, leading with 46 per cent. More than 63,800 candidates sought 17,510 posts, ranging from the presidency to city councillorships.
