This week, Brexit negotiations grind to a halt again as Brussels and the UK draw mutually exclusive red lines on the Irish border problem. We talk to James Forsyth and Dan Hannan on what next for Brexit (00:45). We also look a little deeper into the methods and mission of Bellingcat, the investigators that unveiled the true identities of the Salisbury suspects (13:25). And last, we investigate a sex industry that is trying to become more ethical (25:25).

With James Forsyth, Dan Hannan, Owen Matthews, Mary Dejevsky, Cosmo Landesman, and Renée Denyer.

Presented by Isabel Hardman.

Produced by Cindy Yu and Alastair Thomas.
