The President of Iran (Persian: رییسجمهور ایران Rayis Jomhur-e Irān) is the head of government of the Islamic Republic of Iran. The country's president is the highest popularly elected official in Iran (however, the president is still required to gain the Supreme Leader’s official approval before being sworn in before the Parliament and the Leader also has the power to dismiss the elected president anytime). The President carries out the decrees, and answers to the Supreme Leader of Iran, who functions as the country's head of state. Unlike the executive in other countries, the President of Iran does not have full control over anything, as these are ultimately under the control of the Supreme Leader. Chapter IX of the Constitution of the Islamic Republic of Iran sets forth the qualifications for presidential candidates. The procedures for presidential election and all other elections in Iran are outlined by the Supreme Leader. The President functions as the executive of the decrees and wishes of the Supreme Leader. These include signing treaties and other agreements with foreign countries and international organizations, with Supreme Leader's approval; administering national planning, budget, and state employment affairs, as decreed by the Supreme Leader. The President also appoints the ministers, subject to the approval of Parliament, and the Supreme Leader who can dismiss or reinstate any of the ministers at any time, regardless of the president or parliament's decision. The Supreme Leader Ali Khamenei directly chooses the ministries of Defense, Intelligence and Foreign Affairs, as well as certain other ministries, such as the Science Ministry. Iran’s regional policy is directly controlled by the office of the Supreme Leader with the Ministry of Foreign Affairs’ task limited to protocol and ceremonial occasions. All of Iran’s ambassadors to Arab countries, for example, are chosen by the Quds Corps, which directly reports to the Supreme Leader.
As such, the current long-time Supreme Leader Ali Khamenei, ruling Iran for nearly three decades, has been issuing decrees and making final decisions on economy, environment, foreign policy, national planning, and almost everything else in the country. Khamenei has also made final decisions on the degree of transparency in elections in Iran, and has fired and reinstated Presidential cabinet appointments.
The President of Iran is elected for a four-year term by direct vote and not permitted to run for a third term or serve for more than 8 years in the office.
The current President of Iran is Hassan Rouhani, assumed office on 3 August 2013, after the 2013 Iranian presidential election. He succeeded Mahmoud Ahmadinejad, who served 8 years in office from 2005 to 2013. Rouhani won re-election in the 2017 presidential election.
