Alireza Bikdeli told reporters on Friday that “Considering the time difference, the election will be held for at least 10 hours from 8 am on Friday, and we will continue until the final hours of tonight in most countries.”
He noted facilities have been improved for the election compared to the first round held last week, adding data shows a higher turnout of Iranians living overseas.
Voting got underway at 8 am in Iran (0430 GMT) for over 64 million eligible voters.
Reformist Massoud Pezeshkian and principlist Saeed Jalili, who got most of the votes among the four candidates in the first round but failed to achieve an outright victory, are vying for the top executive post to replace the late president Ebrahim Raisi who died in a helicopter crash in May 19.
