Central to the European idea was the new narrative of a borderless union, with freedom of movement for all European citizens, beyond traditional national narratives. The Brexit referendum and the following highly conflictual negotiations have led to profound uncertainties both on the level of European utopia as a grand historical project and of European citizens’ daily lives. Professor Sigona will discuss the post Brexit-referendum experiences of families with EU27 nationals living in London and their changing feelings of belonging, as well as their plans and strategies regarding future mobility and migration.
