Parliament of the United Kingdom
The Parliament of the United Kingdom of Great Britain and Northern Ireland, commonly known internationally as the UK Parliament, British Parliament, or Westminster Parliament, and domestically simply as Parliament, is the supreme legislative body of the United Kingdom, and the British Overseas Territories. It alone possesses legislative supremacy and thereby ultimate power over all other political bodies in the UK and the overseas territories. Parliament is bicameral but has three parts, consisting of the Sovereign (the Queen-in-Parliament), the House of Lords, and the House of Commons (the primary chamber). The two houses meet in the Palace of Westminster in the City of Westminster, one of the inner boroughs of the capital city, London.
Sovereignty
Within the modern governmental system, internal sovereignty is usually found in states that have public sovereignty and rarely found within a state controlled by an internal sovereign. A form of government that is a little different from both is the UK parliament system. From 1790 to 1859 it was argued that sovereignty in the UK was vested neither in the Crown nor in the people but in the "Monarch in Parliament". This is the origin of the doctrine of parliamentary sovereignty and is usually seen as the fundamental principle of the British constitution. With these principles of parliamentary sovereignty majority control can gain access to unlimited constitutional authority, creating what has been called "elective dictatorship" or "modern autocracy". Public sovereignty in modern governments is a lot more common with examples like the USA, Canada, Australia and India where government is divided into different levels.
