The opposition's allegations of electoral fraud marked Serbia's national elections as people went to the polls to vote for president, parliament and local representation on Sunday.

However, the current president, right-wing populist Aleksandar Vucic, is expected to remain in power, which he has held for a decade via various positions.

At the local level, however, the opposition is expected to be able to secure some victories.

Election fraud reports

Election day has been marked by unrest and rumors of election fraud by the opposition.

The opposition's election controllers are said to have reported so-called ghost votes, votes that are signed with the names of people who are dead or made up.

Reuters reports that activists from the ruling parties have offered money in exchange for votes.

An opposition leader is said to have been attacked outside Vucic's party office in a Belgrade suburb, and a ruling party official has been assaulted in the town of Nis.

One hour before the polls closed, turnout was reported at 55 percent, which is higher than in most Serbian elections, Reuters reports.
