I think it was Radio Scotland. (I switch between 5-Live, Radio 4 and Radio Scotland). It would have been between 7:25 and 8:15. The failings of the business model were, as I recall: 1) All companies having the same outlook and therefore all doing the same thing 2) Over commitment in Downstream activities. 3) Loss of expertise through handing over a great deal of decision making to contractors. 4) Overly focused on increasing reserve balance. I looked at the Chatham House site, hoping to find further material, but so far nothing.
