Subsequent elections were held to approve of the newly-drafted Constitution. Along with the position of the Grand Leader, the constitution also requires that a president be elected every four years, but only those candidates approved indirectly by the Council of Guardians may run for the office. Imam Khomeini himself became instituted as the Grand Leader for life, and officially decreed as the "Leader of the Revolution."
