The 6.6-million-strong electorate will elect a new 250-seat parliament among candidates from 20 lists of political parties and coalitions.
According to the latest opinion polls, parties that have the best chances of winning seats are the Serb Radical Party led by ICTY indictee Vojislav Seselj, the Democratic Party led by the incumbent Serbian President Boris Tadic and the coalition of Prime Minister Vojislav Kostunica's Democratic Party of Serbia and the New Serbia party.
Other lists that may pass the five percent threshold are the G17 Plus and the coalition of the Liberal-Democratic Party led by Cedomir Jovanovic, the Citizens' Alliance led by Natasa Micic, the Social Democratic Union led by Zarko Korac and Social Democratic League of Vojvodina led by Nenad Canak.
The Socialist Party of Serbia of the late Serbian president Slobodan Milosevic, who died in March 2006 during his trial before the UN war crimes tribunal, stands a slim chance of entering the parliament, according to the surveys.
Several leaders of European countries visited Belgrade recently, urging Serbians to elect a democratic government that would be able to integrate the country with Europe.
