A preliminary results shows that, the former rebel commander wanted by Serbia for alleged war crimes has won Kosovo's parliamentary election.
Ramush Haradinaj, a former prime minister, leads a centre-right coalition of parties that emerged from the 1998-99 conflict with Serbia.
With 70% of the votes counted, the electoral commission said his alliance had won about a third of the vote.
The left-wing opposition party Vetevendosje has about 25%, it said.
Kosovo declared independence from Serbia in 2008. It is recognised by the US and most EU countries, but not by Serbia or its ally Russia.
A victory for Mr Haradinaj, leader of the Alliance for the Future of Kosovo, would complicate relations with Serbia, which has issued an international arrest warrant against him for alleged war crimes.
Another centre-right coalition, led by outgoing Prime Minister Isa Mustafa of the Democratic League of Kosovo, stands at 25.8%.
Similarly, Ismet Kryeziu, of the non-governmental group Democracy in Action, warned no party should celebrate too soon.
Mr Mustafa called the snap election last month after his government lost a vote of confidence.
