Iran's Supreme Leader Ali Khamenei said on Wednesday that the turnout in the first round of the country's presidential election was "lower than expected", the semi-official Tasnim news agency reported.
Turnout was about 40%, Iran's interior ministry said - the lowest on record since the 1979 revolution.
"We hope that people's turnout for the second round will be important and a source of pride for the Islamic Republic," Khamenei said, calling upon Iranians to cast their ballot this coming Friday.
Friday's vote will be a tight race between lawmaker Massoud Pezeshkian, the sole moderate in the original field of four candidates, and former Revolutionary Guards member Saeed Jalili.
The election is to elect a successor to President Ebrahim Raisi, who died in a helicopter crash in May.
Khamenei added that the lower-than-expected turnout was due to "several factors" and that claims that non-voters were against the Islamic Republic were "strongly mistaken".
“It is disgraceful for a nation to have a 35% or 40% voter turnout, as happens in some of the nations that you see having presidential elections,” Khamenei said in 2001. “It is obvious that their people do not trust their political system, that they do not care about it and that they have no hope.”
