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.
Democracy in the Middle East
The current political system in Iran was designed to allow Iranians to decide their future by themselves without being oppressed by authorities, but in practice only allows a limited democracy. One of the main problems of Iran's system is the consolidation of too much power in the hands of the Supreme Leader who is elected by the Assembly of Experts for life (unless the Assembly of Experts decides to remove him, which has never happened). The power of the Supreme Leader under Iran's constitution is almost unlimited and unrestricted in practice. This combined with the view that he is the representative of God held by some religious groups, being the head of the security and armed forces, and controlling the official state media (the radio and television are restricted to state radio and television) makes him immune from any kind of criticism and unchallengeable. Critics of the system or the Supreme Leader are punished severely. Critical newspapers and political parties are closed, social and political activists like writers, journalists, human right activists, university students, union leaders, lawyers, and politicians are jailed for unreasonably long periods for making simple criticism against the Supreme Leader, the Islamic Republic system, Islam and Shia doctrines, the government, and other officials. They have been even threatened by death sentence (though all such verdict in recent years have been dropped in higher courts in recent years) and some have been assassinated by the Ministry of Intelligence and militias in the past (no such case has been reported in recent years).
