Orf said that the Interior Ministry had proposed two dates for the 13th presidential elections, and the Guardian Council approved June 18, according to IRNA.

Iranians will choose the successor to President Hassan Rouhani who will have served two four-year terms in office.

Candidates hoping to run for president must apply in early April for approval; the final list is to be announced in early June.

Under Iranian law, an incumbent president cannot run for a third term if he has already served two consecutive terms in office. Rouhani was first elected in 2013 and reelected four years later.

In February, Iran held parliamentary elections. The newly-elected Parliament is dominated by conservative lawmakers.

Rouhani’s administration has been under increasing pressure from the US following Washington’s withdrawal from the 2015 nuclear deal between Iran and world powers and the reimposition of sanctions on Iran. The deal put limits on Iran’s nuclear program in exchange for sanctions relief.
