[ by Melanie Gretchen ] Barclays faced 3 separate internal warnings between 2007 and 2008 regarding conflicts of interest and "patently false" submissions by its staff to the panel that determines the London interbank offered rate.  Coming to light in the bank's $453 million settlement with the CFTC and the UK's Financial Services Authority, the discovery furthered pressure by politicians to change the industry. One executive at a rival bank said he "could not get his head around the fact" that the issue had not initiated consequences.  "At our firm, we would immediately have sent in internal auditors.  I don’t understand why this has not happened."
