Serbian voters headed to the polls on Sunday in a triple election, which is likely to keep the existing government in power.

Some 6.5 million voters are choosing the president, a new parliament and local authorities in the capital, Belgrade, and over a dozen other towns and municipalities.

Opinion surveys ahead of the vote have predicted that President Aleksandar Vucic will win another five-year term and that his right-wing Serbian Progressive Party will yet again dominate the 250-member assembly.

But opposition groups stand a chance to win the majority in Belgrade, analysts say. This would deal a serious blow to the populists' decadeold unchallenged rule in Serbia.

Vucic, a former ultranationalist who has boasted of close ties with Russian President Vladimir Putin, has sought to portray himself as a guarantor of stability amid the turmoil raging in Europe.

After casting his vote in the capital Belgrade for presidential, parliamentary and local elections, Vucic said: "I am confident that people will choose a good future for themselves, their families, and their children. I believe that citizens will choose continued economic progress. As far as I have heard, there has been no problem so far. I personally have a meaningful and important expectation of victory. I think everyone will get what they deserve."

Meanwhile, the presidential candidate of the opposition "United for the Victory of Serbia," Zdravko Ponos, said he expected the elections would mark the beginning of more normal relations in society and the end of artificial divisions, better relations with the environment, a more certain future and more stable life.

Ponos said that Serbia is a "deeply divided society."

Serb Member of the Presidency of Bosnia and Herzegovina Milorad Dodik also participated in the elections by casting his vote at the Consulate General of Serbia in Banja Luka city.

Dodik said that a significant number of citizens across Republika Srpska (one of two entities of Bosnia-Herzegovina) are voting.

"I would like all citizens of Republika Srpska to one day get automatic citizenship of Serbia and to be able to vote for everyone here on this day when elections are held in Serbia. That will be part of my efforts in the future," said Dodik.

In a country that went through a series of wars in the 1990s and a NATO bombing in 1999, fears of a conflict spilling over have played into Vucic's hands.

Though Serbia is formally seeking European Union entry, Vucic has fostered close ties with Russia and China, counting on the Serbs' resentment of the West over the NATO air war.

Serbia has supported a United Nations resolution that condemned the Russian invasion of Ukraine, but Belgrade has not joined the sanctions against Moscow, a historic Slavic ally.

Beleaguered opposition groups have also mostly refrained from publicly advocating a tougher line on Moscow. Russia has supported Serbia's claim on Kosovo, a former province that declared Western-backed independence in 2008.

After boycotting the previous vote in 2020, main opposition parties have said this vote is also far from free and fair because of Vucic's domination over the mainstream media and state institutions.

Vucic’s main opponent in the presidential election comes from a centrist-conservative coalition, United for Victory of Serbia, which comprises the main opposition parties.

Gen. Zdravko Ponos, a Western-educated former army chief of staff, is hoping to push Vucic into a second round in the presidential ballot.

"These elections are going to (bring) serious change in Serbia," Ponos said after casting his ballot. "I hope citizens of Serbia are going to take a chance today," he added.

In the run-up to the vote, reports have emerged of ballots being sent to addresses for people who don't live there, prompting opposition warnings of potential fraud.

The ruling populists have denied manipulating ballots or pressuring voters.

Their standing in the capital has been lower than the rest of the country due partly to a number of corruption-plagued construction projects that have devastated the city's urban core.

A green-left coalition, Moramo, or We Must, is running in the election for the first time, campaigning on the discontent in Belgrade and anger over Serbia's numerous environmental problems.

The group has drawn thousands of people to protests against lithium mining in Serbia and to demand cleaner air, rivers and land.

Since his party came to power in 2012, Vucic has served as defense minister, prime minister and president.

On the eve of the election, some voters in Belgrade said they would like to see a change, at least in the capital city. Others were skeptical that this was possible.

"Honestly, I think the opposition stands no chance," said Srdjan Kovacevic, a resident of Belgrade.

Predrag Rebic said he too expects the central government and the president to remain the same.

"The (Belgrade) mayor will change, that’s what I expect," he said.
