Almost complete results show that the leftist ruling party has won the parliamentary election in Slovakia, but will need coalition partners to form a majority government.

In a shocking development, a neo-Nazi party gained parliamentary seats.

With the votes from more than 98 percent of the almost 6,000 polling stations counted by the Statistics Office early Sunday, the Smer-Social Democracy of Prime Minister Robert Fico, which campaigned on an anti-migrant ticket is a winner with 28.4 percent of the vote, or 49 seats in the 150-seat Parliament.

That represented a significant drop in support from the 2012 election when Smer took 44.4 percent and was able to govern alone.

Eight parties have won seats, including the neo-Nazi People's Party, Our Slovakia, which got 8.1 percent.
