Exit poll data show that Vucic’s conservative party is set to win over 50 percent of votes. Vucic claimed victory late Sunday.
"Serbia will continue along the European path and we will try to speed it up," Vucic told his supporters at the party headquarters.
"As I said before, we will make no compromises and we will preserve our traditional friendship and relations with Russia and China, as well as with the United States and other countries," he stressed.
The Progressive Party’s victory will give it the parliamentary majority and a mandate to go on with reforms needed to join the European Union. Serbia formally applied for EU membership in 2009.
