Three years since the UK left the EU, talks are still going on over trading arrangements. Why are they happening and what has changed since Brexit?

Adam is back in Brussels to mark the anniversary – and we’ve got the whole Brexitcast gang together! There will of course be cake, as well as analysis and memories from the BBC’s Europe editor Katya Adler, and political editors past and present, Laura Kuenssberg and Chris Mason.

We’ve also finally caught up with Michel Barnier! The former EU chief negotiator joins us in London with his insider’s take on the talks and how he sees UK-EU relations moving forwards. It turns out he may have been lured across the Channel by the promise of a full English breakfast.

And the BBC’s global trade correspondent, Dharshini David, explains what we can say about the impact of Brexit on the economy.

This episode of Brexitcast was made by Daniel Wittenberg with Cordelia Hemming, Greg Brosnan and George Crafer. The technical producer was Mike Regaard. The editor is Sam Bonham.
