Undercurrents co-founder Zoe Broughton writes in the Guardian today
The undercover policeman and "environmental activist" Mark Kennedy is giving us covert operatives a bad name. I was first recruited to work undercover back in 1996. Taken to a room, sworn to secrecy, I then spent the next 10 weeks investigating Europe's largest animal-testing laboratory, Huntingdon Life Sciences. I was filming for a Channel 4 documentary. It is not just the police who use spies to gather information; the media and campaigners do too.
