Exactly one year ago, Prime Minister Theresa May expatiated on the subject of citizens’ rights in the post-Brexit EU and UK, memorably telling the Conservative Party Annual Conference that “if you believe you are a citizen of the world, you are a citizen of nowhere. You don’t understand what citizenship means.” Taken in the context of a conference dominated by the decision of the British public to leave the European Union, the audience was left with no doubt that Brexit would represent a re-casting of citizens’ rights, a re-assertion of the exclusivity of United Kingdom citizenship, and a rejection of the creeping internationalism of citizenship that the EU was seen to represent, though the form this transformation would take was still a matter of some conjecture.
