In parliamentary governments, the prime minister is ''always'' a member of the legislature, and is never the [[head of state]]. In the presidential system, the president is ''never'' a member of the legislature, and is always the [[head of state]]. Many countries with a parliamentary system, however, have a head of state who is also called a "president", but without executive power. Other countries with a parliamentary government have a hereditary [[monarch]] as head of state. | In parliamentary governments, the prime minister is ''always'' a member of the legislature, and is never the [[head of state]].
