The Progressive Party of Nikolić and the coalition led by Tadić's Democratic Party are also neck-and neck in the parliamentary election, held the same day.
According to the first official results of the Presidential poll, Nikolić won 25.47% of votes, while Tadić obtained 23.63%. The Socialist leader Ivica Dačić won 16.61%, the leader of the Democratic Party of Serbia Vojislav Koštunica 7.4%, Zoran Stanković, the current Health minister 7.36%, and Čedomir Jovanović, leader of the Liberal Democratic Party got 4.11% of votes.
Meanwhile, the parliamentary vote marked the surge of the former ultranationalist allies of Slobodan Milošević, who rode on voter anger at the country's economic stagnation. Tadić's Democrats polled 38% in the last election in 2008, but were punished this time for an economic downturn that has driven unemployment to 24%.
The Progressive Party took a pro-European stance only after its founding in 2008, when it decided to split from the nationalist Serbian Radical Party. As a result, it has yet to prove its commitment to European integration and democratic standards. The historic leader of the Radical Party Vojislav Šešelj is currently standing trial for war crimes before the Hague tribunal.
Official results on 10 May
The final results of presidential and parliamentary elections will be announced on 10 may in the evening. A 30-day deadline for talks on constituting parliament begins on the same occasion. The Electoral Commission will award mandates to candidates in the same order as were listed on their tickets.
According to preliminary results of parliamentary elections based on 7.46% of polling stations, the coalition "Let's Get Serbian Moving" headed by the Serbian Progressive Party won 24.17% of votes, followed by the coalition "A Choice for Better Serbia" headed by the Democratic Party with 21.29%.
The coalition of the Socialist Party of Serbia - the Party of United Pensioners of Serbia - the United Serbia party collected 16.65% of votes, the Democratic Party of Serbia 7.24%, the United Regions of Serbia movement 7.08%, the coalition "Turnabout" headed by the Liberal Democratic Party 4.94%, the Serbian Radical Party 4.36% and Dveri movement 3.19% of the ballot.
The third-placed Socialist Party (SPS), once led by Milošević, will most likely decide on who forms Serbia's next coalition government. It is widely tipped by analysts to pick the Democratic Party.
