Prime Minister Aleksandar Vucic will again be in charge of forming Serbia's government, according to a statement on the president's website on Monday, a month after snap elections.
"I decided to hand the mandate for the new government to Vucic," said President Tomislav Nikolic, after completing formal consultations with the heads of the parties that won seats.
Vucic and his Progressive Party won 131 of the 250 votes, leaving them the overall victor despite losing 27 seats from the previous parliament.
Six others won seats in parliament by taking at least 5 per cent of the ballots cast, along with 10 representatives of ethnic minorities.
Vucic had called the elections two years early - halfway through his term - saying he wanted a full four-year mandate for the reforms required of Serbia within EU membership talks.
The deadline to compose the new legislature is June 4.
