The 2021 Cambridge Sixth Form Law Conference was recently held online. I was pleased to record a talk for the conference on Constitutional Law. I took ask my title 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. The talk can be viewed on YouTube.
