Jonathan Agnew is joined by Sir Alistair Cook, Michael Vaughan and Jeremy Coney for reaction to New Zealand's disciplined display on day two at Edgbaston. England Bowling Coach John Lewis gives his reaction of the day's play, and Jonathan Agnew talks to England analyst Nathan Leamon and Ben Jones from CricViz about why the ball didn't swing as much as the conditions of the day suggested it would, as well as their new book looking into how cricket actually works.
