The Financial Services Authority (FSA), the UK markets regulator, has fined retail banks for violating money laundering regulations but plans to broaden its policing to focus on other market areas.

A spokesman for the FSA said: "We will be looking to widen our enquiries into other areas. We have been looking primarily at large retail banks but our remit extends across the whole regulated sector, including insurance companies, investment banks, brokers and independent financial analysts. The market should expect cases that concern different kinds of business."
