I took part yesterday in a special live edition of Law in Action on BBC Radio 4. Professor Catherine Barnard, Professor Steve Peers and I discussed the legal and constitutional implications of Brexit with presenter Joshua Rosenberg. We covered a broad range of matters —hopefully in a way that was accessible to an equally broad range of listeners. In particular, we considered the (surprisingly) thorny questions of when, how and by whom the Article 50 withdrawal process might be triggered, the role that the UK’s devolved legislatures might play in this regard, what the options might be for the UK’s future relationship with the EU (and, in particular, what membership of the European Economic Area would look life), and how the mechanics of Brexit would work in terms of the UK’s legal system. The programme is available on the BBC Radio 4 website.
