Filip Vujanovic from the Democratic Party of Socialists is heading towards an overwhelming victory, according to preliminary results released today.
"We can say with certainty that Filip Vujanovic has become president with more than 65% of the vote cast," Zlatko Vujovic from independent observer group Centre for Monitoring said.
Vujanovic is the speaker of Montenegro's parliament and a member of the governing Democratic Party of Socialists (DPS). The party embraces social democratic values and has contacts with Western European social democratic parties and foundations.
Vujanovic won presidential elections in December and February, but because less than half the electorate turned out to vote the results were cancelled on both occasions. But that law has been amended in favour of a simple majority of the votes cast. About 48% of some 456,000 eligible voters had cast their ballots on 11 May.
Montenegro has been without a president since November when the then incumbent, Milo Djukanovic, became prime minister - a post holding more power than president.
