A parliamentary system is a system of democratic governance of a state in which the executive branch derives its democratic legitimacy from, and is held accountable to, the legislature; the executive and legislative branches are thus interconnected. In a parliamentary system, the head of state is normally a different person from the head of government. This is in contrast to a presidential system in a democracy, where the head of state often is also the head of government, and most importantly: the executive branch does not derive its democratic legitimacy from the legislature. Countries with parliamentary systems may be constitutional monarchies, where a monarch is the ceremonial head of state while the head of government is almost always a member of the legislature, or parliamentary republics, where a mostly ceremonial president is the head of state while the head of government is regularly from the legislature. In a few parliamentary republics, such as South Africa and Botswana, the head of government is also head of state, but is elected by and is answerable to the legislature. Wikipedia [ - ]
