A Written Constitution A written constitution is a formal document which defines the nature of constitutional agreements; These theses include rules that govern the political system and the rights of citizens and governments in a codified form. The constitution of the United Kingdom is unwritten as it does not come from any single written document, but derives from a number of sources which can be seen as written and partly unwritten, examples of this include the conventions , acts of authority, Acts of Parliament, EU law and common law.
