Having gone through a formal qualification process by Iran’s Constitutional Council, over 12,000 candidates, including dozens of Iranians from the religious minorities, are running for the parliament.
A total of 144 clergymen have also been chosen as the final candidates for the Assembly of Experts elections.
There are 290 seats in the Iranian Parliament, known as Majlis, elected by direct vote of people in nationwide elections for four years.
