[The most powerful political office in the Islamic Republic of Iran is that of the Supreme Leader, of which there have been two: the founder of the Islamic Republic, Ayatollah Ruhollah Khomeini, and his successor, Ayatollah Ali Khamenei. The Supreme Leader is appointed and supervised by Assembly of Experts. The Assembly of Experts is a publicly elected body, given that the right to stand as candidate is severely limited by the Guardian Council consisting of six clerics appointed by the Supreme Leader and six lawyers nominated by the head of the judicial system of Iran (himself selected by the Supreme Leader). The Supreme leader is the Head of State with some Executive powers related to Defense, Religious affairs and Guardian Council.]
