Frequently Asked Questions (FAQ)

Unlike countries with a single written constitution document, the UK has an uncodified constitution derived from multiple sources: Statute Law (Acts of Parliament), Common Law precedents, Royal Prerogative, Conventions, and historical legal documents like Magna Carta.

Parliamentary Sovereignty is the core principle of the UK constitution. It dictates that the UK Parliament is the supreme legal authority, which can create or repeal any law, and no court can overrule an Act of Parliament.
