This week's episode is all about the United Kingdom leaving the European Union. With me for a second time is Aalt Willem Heringa - an expert in his field. If you haven't listened to our episode on constitutions yet, you might want to do that first.

Aalt Willem is Full Professor of Comparative Constitutional Law at Maastricht University and recently started a research blog platform called Law Blogs Maastricht.

We talk about: the court rulings on Brexit, the concept of sovereignty, a Scottish independence, Gorden Brown's federalism idea, the upcoming negotiations, and much more.
