In today's world, people have unprecedented access to vast amounts of news in real time. However, investigative journalism is not simply passing on news in the form of information that already exists. It refers to material that is only available as a consequence of journalistic intervention. Such intervention can take various forms including extensive research, interviews and the exploration of different sources of information, all often on a confidential basis. It can require the journalist to risk their credibility, their careers and even their personal safety.

We look at the increasing role investigative journalism plays in shining a light on fraudulent activity the world over.
