Does the UK have a written constitution?

The UK does not have a single, formal written constitution that consolidates laws and principles in one comprehensive document. Instead, its constitution is considered "unwritten" in the traditional sense, meaning it is not codified in a single, accessible text. Instead, it comprises a mixture of statutes, common law, conventions, treaties, and works of authority. These various sources contribute to the constitutional framework but are dispersed throughout different legal texts and historical documents.

This system allows for a flexible constitution that can evolve over time through legislation and judicial decisions, adapting to changing societal needs and political contexts. Consequently, the absence of a singular, codified constitution is a defining feature of the UK's constitutional setup, differentiating it from many other countries that do have comprehensive written constitutions.
