head of state is the Supreme Leader, to whom the president is subordinate. Other executive positions Sub-national President can also be the title of the chief executive at a lower administrative level, such as the parish presidents of the parishes of the U.S. state of Louisiana, the presiding member of city council for villages in the U.S. state of Illinois, or the municipal presidents of Mexico's municipalities.
