Kosovo's opposition has contested the election of the new president at the Constitutional Court, arguing that there were irregularities during the voting.

Three lawmakers of the three opposition political parties handed over the complaint at the court on Friday.

A week ago, Parliament elected Hashim Thaci, former foreign minister and ex-leader of the governing Democratic Party of Kosovo, as the country's new president in the absence of nearly all opposition lawmakers.

After disrupting the session with tear gas many opposition lawmakers were suspended. Others left and only one remained for the vote.

The opposition has been disrupting the chamber since last September to protest a deal between Kosovo and Serbia that gives more powers to ethnic Serbs in Kosovo. The opposition also rejects a border demarcation pact with Montenegro.
