British constitution (unwritten)

The British constitution is a set of rules and principles that govern the UK’s political system, but unlike many countries, it is not codified in a single written document. Instead, it develops from statutes (laws passed by Parliament), common law (court decisions), conventions (customary practices), and certain historical documents. This flexible, "unwritten" nature allows for adaptability over time. It provides the framework for how government operates, defines the powers of institutions like Parliament and the monarchy, and protects citizens’ rights, all based on these diverse sources rather than a single formal constitution.
