Reformist-backed presidential candidate Hassan Rowhani is leading the Iranian election with more than 4.1 million votes.
Iranian Interior Ministry said on Saturday that more than 8 million votes were counted and Rowhani received around 51 percent of the total votes counted so far.
Rowhani is followed by Tehran Mayor Mohammad Baqer Qalibaf with more than 1.3 million votes and top nuclear negotiator Saeed Jalili with more than 1 million votes.
Except for the only reformist candidate Hasan Rowhani, the remaining candidates are conservatives close to Iran's supreme leader, Ayatollah Khamenei.
If Rowhani does not take above the 50 percent of the vote he will need a second round run-off on June 21.
The 6 candidates racing to be elected as the new president of Iran are the only reformist candidate Hasan Rowhani, Tehran Mayor Mohammad Bagher Qalibaf, Secretary of Iran's Supreme National Security Council Saeed Jalili, top adviser to Supreme Leader Khamenei on international affairs Ali Akbar Velayati, former chief of Iran's Revolutionary Guard Mohsen Rezaei, and former oil and telecommunications minister Mohammad Gharazi.
Except for the only reformist candidate Hasan Rowhani, the remaining candidates are conservatives close to Iran's supreme leader, Ayatollah Khamenei.
