The official IRNA news agency said today that prospective candidates can register through the end of Saturday. They will then be vetted by the Guardian Council, a clerical body that will announce a final list of candidates by April 27.
President Hassan Rouhani, a moderate, is eligible to run for another term. Ebrahim Raisi, a hard-line cleric close to Supreme Leader Ayatollah Ali Khamenei, and Hamid Baghaei, a close ally of former hard-line President Mahmoud Ahmadinejad, have announced plans to run.
The election is expected to serve as a referendum on the 2015 nuclear agreement with world powers, under which Iran agreed to curb its uranium enrichment in exchange for the lifting of international sanctions.
