BELGRADE — Serbian voters on Sunday gave 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, according to an exit poll.
The Belgrade-based CeSID polling group said the Serbian Progressive Party won about 160 seats in the country’s 250-seat Parliament. Its coalition partner in the current Serbian government, the Serbian Socialist Party, was second with about 50 seats.
The rest of the seats went to the pro-Western Democratic Party and the New Democratic Party of former president Boris Tadic.
The Progressive Party is expected to choose as its leader Aleksandar Vucic — a former hard-line, pro-Russian nationalist who has become a pro-EU advocate — as prime minister.
In his victory speech, Vucic pledged to vigorously fight corruption and crime and revive the economy in the troubled Balkan nation of about 7 million people.
‘‘We are facing tough reforms,’’ Vucic said.
The leader of the Socialists, Ivica Dacic, is the prime minister in the outgoing coalition.
Turnout was about 52 percent, slightly less than during the 2012 parliamentary election that brought the Progressives, former allies of late Serbian strongman Slobodan Milosevic, back to power in Serbia.
