BELGRADE, Serbia — An independent poll says Serbs have given a landslide victory in a parliamentary election to the ruling center-right party that has vowed to overhaul the nation’s struggling economy and push for membership in the European Union.

The Belgrade-based CeSID polling group says the Serbian Progressive Party won about 160 seats in in the country’s 250-seat parliament. Second is their coalition partner in the current Serbian government, the Serbian Socialist Party, with about 50 seats.
