Constitution of the United Kingdom
Uncodified constitution based on statutes, conventions, and judicial principles.
The constitution of the United Kingdom comprises the written and unwritten arrangements that establish the United Kingdom of Great Britain and Northern Ireland as a political body. Unlike in most countries, no official attempt has been made to codify such arrangements into a single document, thus it is known as an uncodified constitution. This enables the constitution to be easily changed as no provisions are formally entrenched.

Reader's Guide
The British constitution is significant because it demonstrates a flexible, uncodified system that adapts through political and legal processes rather than a single entrenched document. Its core principles—parliamentary sovereignty, the rule of law, democracy, and adherence to international law—are recognized by the Supreme Court. Parliament can make or unmake any law, and courts cannot invalidate Acts of Parliament, though they can declare incompatibility with the European Convention on Human Rights. Its legacy includes influencing other common law systems and providing a model of constitutional evolution without formal codification.

Frequently Asked Questions
What is the Constitution of the United Kingdom?
It is the collection of written and unwritten rules that define how the United Kingdom of Great Britain and Northern Ireland operates as a political entity. Rather than a single written text, it draws on statutes, conventions, and judicial principles to structure governance.
Why is the UK Constitution called uncodified?
No single official document has ever been produced to bundle all constitutional rules together, so the arrangements remain spread across multiple sources. This structure also means no provision is formally entrenched, allowing the constitution to be amended relatively easily through ordinary legislative process.
How does the UK Constitution differ from most other countries' constitutions?
While most nations rely on a single codified document that is deliberately difficult to amend, the UK operates a flexible, uncodified system of statutes and conventions. This makes it one of the few major political bodies without a formally entrenched constitutional text.
What is the governing principle of the UK Constitution?
Parliamentary sovereignty sits at the heart of the system, meaning that Parliament holds supreme legislative authority over all other bodies. The Supreme Court of the United Kingdom serves as the highest court within this constitutional framework.
