UK System

The United Kingdom is home to one of the world's oldest parliamentary democracies. Whilst the Monarch is the official Head of State and signs bills into law, power over making legislation lies with the two chambers of Parliament; the House of Commons and the House of Lords, which meet at Westminster. In addition, the UK has devolved assemblies in Scotland, Wales and Northern Ireland, which have power over various aspects of the law within their respective borders.

This section contains information about how the various institutions of government in the UK function and interact.
