Around 51 million eligible voters in Iran are getting ready to cast their votes in the Friday presidential election as the six candidates wrapped up their final day of campaigning across the country on Wednesday.

The fourth city and rural council elections are also scheduled to be held on Friday.

Ahead of the vote, the national opinion polls indicate that more than 60 percent of the eligible voters will take part in the country's 11th presidential election. The Iranian voters will have to choose among six candidates who have stayed in the race.

Recent polls also suggest that presidential election might go for a run-off, setting the stage for a fierce race between the two top candidates.

Under the election law, a presidential candidate must obtain more than 50 percent of the votes in the initial round to win outright. Otherwise, the two top candidates will face each other in a second round of voting on June 21.

The six candidates in Iran’s presidential election are President of the Expediency Council’s Center for Strategic Research Hassan Rohani, Supreme National Security Council Secretary Saeed Jalili, Expediency Council Secretary Mohsen Rezaei, Tehran Mayor Mohammad Baqer Qalibaf, former Foreign Minister Ali Akbar Velayati, and former Telecommunications Minister Mohammad Gharazi.

Former Majlis Speaker Gholam Ali Haddad-Adel and former First Vice President Mohammad Reza Aref withdrew their candidacies earlier this week.
