Mark Kennedy in the twilight zone

Corporate spies operate in extreme secrecy, but what was police spy Mark Kennedy doing in this furtive world?

We are planning to devote one of the chapters in the book to the subject of corporate spies. Of course, it is a business which loves the shadows, so it is difficult to know exactly how many of them are out there or what they are doing.

Occasionally however some of them are dragged into the sunlight. We know for example about the activities of Toby Kendall who attempted to infiltrate the environmental group, Plane Stupid. Another was Martin Hogbin who was alleged to have penetrated the Campaign Against the Arms Trade for six years.

We plan to look at how corporations have for decades hired spies to infiltrate campaigns which they fear threaten their business. (more on guardian.co.uk)
