The EU is entering into unchartered waters following the United Kingdom's unprecedented decision to issue a notice of withdrawal of its membership. Now that the formal process of Brexit has begun, this seminar will discuss what is at stake in the complex negotiations that will unfold over the next two years and how they should be conducted. The UK has, from the date of its accession, been an "awkward partner" in the EU, often accused of holding back the integration process, will it now be an awkward leaver? Professor Kenner will examine these questions from the perspective of the UK and the EU 27. The talk will explore the scope of the possible withdrawal agreement, the retention of rights of EU citizens in the UK and UK citizens in the EU, the implications for the border and peace in Ireland, the impact of the Brexit negotiations on the future make up of the UK following the announcement of another referendum on independence for Scotland, and future trade relations between the UK and the EU and also between the UK and the US post-Brexit. Finally, the possibility of reversing Brexit through a second referendum, or of the UK rejoining the EU after leaving, will be analysed.
