Goldman Sachs has detailed the members of the committee it has set up to look at the bank’s business practices a week after Lloyd Blankfein, chairman and chief executive, said the firm need to renew its core business principles.

At the bank's annual shareholder meeting Blankfein said: "The last few weeks have been difficult and disappointing. Questions have been raised that have gone to the heart of our most fundamental value: how we treat our clients."
