Voters in Estonia were casting their ballots Sunday in a parliamentary election that is expected to return incumbent Prime Minister Andrus Ansip to power, dpa reported.
Ansip's Reform Party faces its main challenges from the Centre Party, Social Democrats and Reform's current coalition partner, IRL.
Voting stations opened at 9 am (0700 GMT) and were to close at 8 pm with turnout expected to exceed 60 per cent despite grey weather conditions.
More than 27 per cent of the electorate in the country of 1.3 million inhabitants had already voted prior to polling day, with more than 140,000 people casting their votes online.
Estonia was the first nation to introduce so-called "e-voting" in parliamentary elections in 2005.
The result of the election is expected to be clear by midnight.
