Great Britain and its political institutions

Great Britain is a constitutional monarchy. The British constitution has evolved over many centuries. Unlike the constitutions of most other countries, it is not set out in any single document. Instead, it is made of statute law, common law and conventions. Conventions are rules and practices which are not legally enforceable but which are regarded as indispensable to the working of government; many are derived from historical events through which the British system of government has evolved. The constitution can be altered by Act of Government, or by general agreement to alter a convention. It is thus adaptable to changing political conditions. The organs of government overlap but can be easily distinguished.
