At the 2021 Cambridge Sixth Form Law Conference, I gave a talk that explored the question: ‘Does the UK have a constitution?’ The question is worth asking — and attempting to answer — for at least a couple of reasons. First, the fact that the UK lacks a ‘written constitution’ not infrequently leads to the misapprehension that the UK lack any constitution. In truth, the UK does have a constitution, albeit that it is quite different from those of many other countries. That leads on to the second point: namely, the nature of the differences between the constitution of UK and the constitutions that are often found elsewhere. In the talk, I explore some of those differences — and, in doing so, seek to show what it is about the UK’s constitutional arrangements that make them not only distinctive but also absorbing for those who study them.
