PRAGUE, Oct. 27 (Xinhua) -- Czech's Social Democratic Party (CSSD) led the country's parliamentary elections on Saturday, preliminary results showed.
The CSSD garnered 50 seats in the 200-seat lower house of Parliament, according to the Czech Statistics Office.
A newly-formed party ANO, led by business tycoon Andrej Babis, received 47 seats, followed by the Communist party (KSCM) with 33 seats.
The official results of the elections will be announced on Oct. 30.
The Social Democrats, out of power since 2006, had said they wanted to form a government backed by the Communists.
But with a far worse result than expected - earlier opinion polls suggested the CSSD could win 30 to 40 percent of the vote - the Social Democrats might need support from other smaller parties.
The snap elections were called after former prime minister Petr Necas resigned in June amid a corruption scandal.
The polls were supposed to bring stability and a government of strength to the Czech Republic.
But building a coalition might be extremely difficult for any party, and even a best case scenario would require a minimum of three parties, most likely from different sides of politics, meaning such a government will be fractious and difficult to lead.
