Iran
After the Supreme Leader, the Constitution defines the President of Iran as the highest state authority. The President is elected by universal suffrage for a term of four years, however, the president is still required to gain the Leader's official approval before being sworn in before the Parliament (Majlis). The Leader also has the power to dismiss the elected president anytime. The President can only be re-elected for one term.
The President is responsible for the implementation of the constitution, and for the exercise of executive powers in implementing the decrees and general policies as outlined by the Supreme Leader, except for matters directly related to the Supreme Leader, who has the final say in all matters. 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 affairs such as signing treaties and other international agreements, and administering national planning, budget, and state employment affairs, all as approved by the Supreme Leader.
Mir-Hossein Mousavi
On 28 July 1989, the constitution was amended and approved by Iranian voters in a national referendum with a 97% yes vote. At this time, Mehdi Karrubi had been elected as the new speaker of the parliament, to whom the amended constitution was declared. One of these amendments abolished the position of Prime Minister. Rafsanjani was elected as the fourth president of Iran on 28 July 1989, and became the president on 3 August 1989. Mousavi's premiership ended on the same date. Mousavi was not invited to be a participant in the new government headed by Rafsanjani, and disappeared from the public sphere.
