Presidential system

A presidential system, or single executive system, is a form of government in which a head of government (president) leads an executive branch that is separate from the legislative branch. This head of government is in most cases also the head of state. In presidential countries, the head of government is elected and is not responsible to the legislature, which cannot (usually) in normal circumstances dismiss it. Such dismissal is possible, however, in uncommon cases, often through impeachment.
