Votes are being counted in Sri Lanka's first presidential election since Tamil Tiger rebels were defeated after more than 25 years of civil war.
Election day passed largely peacefully despite several minor bomb blasts.
President Mahinda Rajapaksa faces a close contest against his bitter rival, former army chief Gen Sarath Fonseka. Both men say they expect to win.
The former allies fell out after the war ended last year. Results are due on Wednesday. Turnout was over 60%.
BBC correspondents say with the ethnic Sinhalese vote split between the two men, Tamil and Muslim minorities could play a decisive part in the outcome.
If no candidate has 50% plus one vote after the first count, second preferences will be tallied and the candidate with the greatest number of votes wins.
