Promises that sovereignty would be regained, immigration and asylum controlled, and national identity reasserted were central to the Brexit referendum campaign of 2016 and the ultimate decision to leave the EU. In debates on EU membership, protection, labour, and other forms of migration were frequently conflated and portrayed as being ‘out of control’. Post-Brexit, these issues remain at the centre of political debate and legal change, both in the UK and in European states. In this seminar, we trace pre- and post-Brexit legal developments in UK and EU asylum and migration law, mapping change and analysing developments.
