Britain is one of the oldest democracies in the world, which has gradually evolved from Magna Carta in 1215 to the modern time. But one thing significantly differs the UK from all other democratic countries- that is its Constitution [which is a set of principles that establishes the distribution of power within a political system, the limits of government jurisdiction, the rights of citizens and the method of amending the Constitution itself].

But does the UK really need to “catch up with the modern world” and create a codified Constitution? To give an answer to this question we need to look at several issues. These are: sovereignty of the Constitution; relationships between branches of the government; clarity of the Constitution.
