A total of 80 Iranians had applied to become candidates for the presidential election later this month.
Iran on Sunday announced six candidates who had been approved by the Guardian Council, with only one of the candidates coming from the reformist camp.
The six candidates, mostly conservatives,have been approved to run in the June 28 presidential election to replace President Ebrahim Raisi.
Raisi was killed in a helicopter crash in country’s far northwest last month.
The candidates were chosen by the Guardian Council, which oversees elections in the Islamic Republic, from 80 registered hopefuls, the Interior Ministry said.
Of the six candidates, five are considered hardliners and only one is from the reformist camp.
Mahmoud Ahmadinejad, a firebrand populist known for his crackdowns following his controversial 2009 election, was again banned from running. No women were approved as candidates.
Others, including the moderate former speaker of parliament, Ali Larijani, and Vahid Haghanian, a former commander in Iran’s Revolutionary Guards, were also barred from running.
Four women also registered to run, but were disqualified. This has been the case in every presidential election since the 1979 Islamic Revolution.
