Serbs go to the polls on Sunday in a fourth attempt in less than two years to elect a new president. No outright winner is expected so a runoff is likely at the end of the month. The election is being seen as something of a contest between nationalists and democrats.
Tomislav Nikolic: Hopes for Greater Serbia
Q: Who is standing?
There are 15 candidates overall. Nationalist Tomislav Nikolic, whose Serbian Radical Party (SRS) won the December parliamentary elections, is frontrunner.
Either the Democratic Party's Boris Tadic or the Serbian ruling coalition's Dragan Marsicanin are most likely to enter a second round with Nikolic.
Experts believe a second round is almost a certainty, although a low turnout could in theory result in a Nikolic victory. Many voters are still undecided so the outcome is difficult to predict.
Q: What's the system?
The election law has been changed to remove the 50-per-cent turnout requirement for polling to be valid. This was why three previous polls failed.
A candidate must win at least 50 per cent of votes in the first round to get elected. Otherwise the two candidates with the most votes enter a second round. This is held 14 days after the first and is decided by a simple majority.
The president is elected for five years and cannot hold the post for more than two terms. A political party or public group can put up a candidate if they submit over 10,000 signatures to the electoral commission.
Q: Who can vote?
Altogether there are 6,531,549 registered voters. Serbs will also be able to vote at 241 polling stations in Kosovo, six fewer than last time as Serbs left some parts of Kosovo after riots in March.
OPNION POLL ON 3 JUNE
Tomislav Nikolic 34%
Boris Tadic 27%
Dragan Marsicanin 17%
Bogoljub Karic 9%
Ivica Dacic 4%
Recent amendments to the Election Law gave the vote to the Serbian Diaspora for the first time. But interest among Serbs abroad has been slight. Only about 10,000 people registered to vote, in around 100 polling stations in 18 countries.
