Report: A new Magna Carta?

King’s College London have produced three blueprints of what form a codified constitution for the UK could take: a Constitutional Code (a non-legal document setting out the existing constitutional arrangements), a Constitutional Consolidation Act (a collection of existing laws on the constitution), and a Written Constitution (a document of basic law by which the UK would be governed, including some changes to existing constitutional arrangements). In order to help you compare and contrast these three blueprints, we have selected some common themes that you might want to consider.  By clicking on a theme below, you can read what each blueprint says about that subject.

Head of State

Prime Minister

The role of the judiciary within the UK’s constitutional arrangements is not currently set out in a single document.  Like the constitution itself, it has evolved from a variety of sources, including Acts of Parliament, common law precedents and conventions. The Committee has already produced a report on the “Constitutional role of the judiciary if there were a codified constitution”.  To compare and contrast how the blueprints handle the topic, see
