Seven years after the tragedy, the inquiry into the Grenfell fire has published its report. What did we learn from it and who bears responsibility? And, with thousands of buildings still believed to contain flammable cladding, what should happen next? With such important lessons to be learnt, why do British inquiries take so long? Also on the podcast, a look at the first PMQs following summer recess and the Tory leadership election. James Heale speaks to Isabel Hardman and Liam Halligan, Telegraph columnist and author of Home Truths. Produced by Patrick Gibbons.
