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.
National Front (Iran)
On 16 January, the Shah left the country, amid rejoicing among the populace, and on 11 February, the regime collapsed and Ayatollah Khomeini became the political leader of Iran. At first the National Front supported the new Provisional Revolutionary Government and the establishment of the Islamic Republic. But the joint statement with Sanjabi notwithstanding, Khomeini "explicitly refused to put the same word, democracy, into either the title of the Republic or its constitution." Within a short time, it became clear that Ayatollah Khomeini's model of an Islamic society was modeled not on democracy, but on theocratic rule of Islamic jurists (or velayat-e faqih), and traditional Islamic sharia law.
