Congressional systemA congressional system is a form of government that features a powerful, lawmaking congress as one of its main organs.
A congressional government is different from a parliamentary government as it does not have a Prime Minister. The congress may have a nominal head, but usually the powers of Head of State and Head of Government rest with a president who is not a member of the legislative branch. For this reason, the term congressional system is often used interchangably with presidential system.
