According to unofficial results, former Kosovo Albanian guerrilla leader’s party won the elections for the parliament on Sunday.

Hashim Thaci promised Kosovo the independence from Serbia. His party, the Democratic Party (PDK), is leading with 35 percent of the vote, with 90 percent of the ballots counted, Reuters reports.

The Democratic League of Kosovo (LDK), President Fatmir Sejdiu’s party, has only 22 percent of the vote and is in second place.

PDK will probably have to form a coalition with the LDK, according to an official from the PDK.

Thaci is an ex-leader of the Kosovo Liberation Army who faced accusations of terrorism by former Serb leader Slobodan Milosevic and was forced to hide.

He said that his first priority will be to declare Kosovo independent from Serbia.

Kosovo is a province of Serbia having a population mainly made up of Ethnic-Albanians.

A small Serbian minority is present in the country and is under the U.N. administration since 1999.

Albanians and Serbs received a deadline from the United Nations that the future of the province will be decided until December 10.

Thaci addressed his supporters in Prisitna, capital of Kosovo, late Saturday, saying: "These elections are not about Kosovo's status. We will declare independence immediately after December 10.”

Still, it was recorded a low turnout at the polls. Around 45 percent of the 1.5 million inhabitants voted on Saturday.

The Serbs boycotted the poll because they want Kosovo to remain in Serbia, CNN reports.

According to Sven Lindholm, a spokesman for the Organization for Security and Cooperation in Europe, the international mediation body, the preparation for the vote was hampered by the Serbian authorities.

The Serbian government didn’t allow for the schools in the region controlled by Serbia to be used as polling stations.

He said: “We were forced to set up mobile units. It was an inconvenience but we got over it.”
