The official results were expected to be announced by May 15, but were held up until a re-vote could take place at three polling stations following breaches in voting procedures.
Serbia's pro-Western Democrat Party won 102 seats (38.4%) in the 250-seat parliament, with Tomislav Nikolic's Radical Party garnering 78 seats (29.45%). The results mean that Tadic's party failed to win an outright majority required to push through his pro-Western policies and move closer to EU membership.
Nikolic's nationalist party is expected to join forces with outgoing prime minister Vojislav Kostunica's Democratic Party with 30 seats (11.61%), which will leave both pro-Western Tadic and Nikolic chasing coalitions with the Socialists and Liberals to try and get the necessary 126 seats needed for a parliamentary majority.
A coalition including the Socialist Party of Serbia, the Party of United Pensioners of Serbia and United Serbia took 20 seats (7.58% of the vote), and the Liberal Democratic Party won 13 seats (5.24%).
The turnout was 61.35%, or 4.1 million voters.
