The candidate of Serbian Prime Minister Vojislav Kostunica's Democratic Party of Serbia came in third with 14.7 percent. Kostunica's partners in his minority government coalition jointly collected less than 4 percent.
The results, announced by the independent election monitoring organization, were based on a count of around half of the votes from a representative sample.
The figures for local parliaments in nearly 150 Serbian municipalities are expected later.
