"Compliance has not been seen as a serious enough specialist activity," Walker said. "Our track record in culture has not been good. It's important for us all to have a concept of culture, conduct and compliance."
Compliance officers, along with internal auditors, have long been seen as vulnerable to pressure from sales staff not to put too much grit in the profit-making machine.

"It's timely for the market to be examined."
