Belgrade: Serbia’s presidential polls opened on Sunday in a tight race between pro-Western president Boris Tadic and hardline challenger Tomislav Nikolic. 

Preliminary results showed Nikolic slightly ahead of Tadic, but final results are not expected until Thursday.

At least 6.7 million voters are to choose among nine candidates a new president for a five-year mandate.

The latest polls and analysts say none will get a first round majority and Tadic and Nikolic will fight a run-off on February 3, with the winner most likely to be eligible to draw third-party votes.
