David Runciman talks to Glen Rangwala on the day after the publication of the Chilcot report, about what's in it and what's missing. Glen exposed the 'dodgy dossier' at the time of the Iraq war and is a leading expert on the politics of the region. They discuss what are the real lessons to learn from Chilcot and why the problems extend beyond a few individuals. They also examine Tony Blair's claims about what Iraq would be like if Saddam were still there. Plus, was Jeremy Corbyn the right person to apologise?
