The poll, which surveyed 17,000 voters at 400 precincts, claimed a margin of error of 2 percentage points, indicating Poroshenko clearly passed the 50-per cent mark needed to win without a runoff. It was conducted by the Razumkov Center, Kiev International Sociology Institute and the Democratic Initiatives Foundation.
The election came three months after the country's pro-Russia leader fled in February, chased from power by months of protests over corruption and his decision to reject a pact with the European Union and forge closer ties with Moscow, and two months after Russia annexed Crimea.
Yet the question of who was able to vote today loomed large over the democratic process. Some 35.5 million Ukrainians were eligible to vote, but separatists in the eastern Donetsk and Luhansk regions, which have 5.1 million voters, said they will not hold the vote because they are no longer part of Ukraine.
Little voting was taking place in the east. The regional administration in Donetsk said only 426 of 2,430 polling stations in the region were open today, and none in the city of Donetsk, which has 1 million people. There was no voting in the city of Luhansk either, but some stations were open in the wider Luhansk region.
Fighting broke out today in the Luhansk town of Novoaidar, where an AP reporter heard heavy gunfire. Areas north of the town, 50 kilometres north of the rebel-held city of Luhansk, are under the control of pro-government forces.
