In order for any state to have control and keep order over their respective boundaries the powers of that state must have a form of decision-making structure in place. Through the ages several types of decision-making structures have been used from democratic to authoritarian. One of the oldest types of these that are still in existence today is parliamentary which is used in several places worldwide. Even though the basic parliamentary structures of government are implemented in many countries, there are many variations to be seen. .
There are many basic and universal ideas behind the parliamentary democracy and these basic structures are just a framework that many governments have built upon and derived from. A parliamentary democracy is a form of government ruled by a nationally elected legislature that is chosen in a free, open election system. The parliament holds supreme power, with the executive power held by a prime minister who is usually the leader of the majority political party, or coalition of parties, in the legislature. Strength of the democratic parliamentary system is that the people are given a voice in choosing their leaders based on their political beliefs. It provides for stability since the executive and legislative branches are of the same political party. A disadvantage of the parliamentary system is that it lacks checks and balances between the branches of government. Parliamentary systems can more readily become dictatorships, as happened in Germany in 1933. Another disadvantage is!.
that effective government can be stalemated if there are too many political parties in the legislature that can't agree on a prime minister.(GUY 98-107) .
