With just six weeks to go until Brexit - and in the week in which the International Trade Secretary Dr Liam Fox signed the 4th of the 40 deals he expects to seal before 29th March - Adam Boulton and guests discuss post-Brexit trade, tariffs and the relationship with the World Trade Organisation. They also examine the latest controversy involving the Transport Secretary Chris Grayling after a multi-million pound shipping contract - to a company with no ships - was cancelled. Joining Adam this week are the Sky's business correspondent Adam Parsons, the Head of Europe and Trade Policy at the Institute of Directors Allie Rennison, Sky's political reporter Rob Powell and the head of Sky Data Harry Carr.
