EU citizens living in the United Kingdom and EU citizens-qua-UK nationals living in other Member States following the referendum on the UK’s continued membership of the EU on 23 June 2016 became ‘the numbered’ 'others'. Their identities were redefined overnight not by them, but by state authorities and their co-EU citizens. In this chapter, I trace the process of 'othering' of EU citizens, which had started several years before the referendum in 2016, and unravel the key moments, forces, and strategies that made it possible by utilising a discursive theoretical approach. I argue that the quest for EU citizens’ rights in the UK under Brexit, just like the quest for migrants’ rights, is a quest as much for the realisation of the fundamental status of Union citizenship as for the effectiveness of the principle of respect for human dignity.
