We're back after after the summer break but just to shake things up, Adam Boulton and guests discuss Brexit, the antisemitism crisis engulfing the Labour Party and the apparent internal dissent from an anonymous source in Donald Trump's White House. A fascinating week in politics and joining Adam to assess the big issues are Sky's deputy political editor Beth Rigby, Tony Blair's former adviser Matthew Doyle, The Telegraph's Brexit editor Dia Chakravarty and our resident statto, the Head of Sky Data Harry Carr.
