I would like to thank the World Ethical Data Forum and Foundation for its support in writing this book, not least the founder and CEO, John Marshall, and our privacy expert, Sander Venema.

Last, but not least, I think both MI5 and David Shayler deserve a mention. Without those experiences, I should never have started down this path of discovery…
