A police officer who for seven years lived deep undercover at the heart of the environmental protest movement, travelling to 22 countries gleaning information and playing a frontline role in some of the most high-profile confrontations, has quit the Met, telling his friends that what he did was wrong.
PC Mark Kennedy, a Metropolitan police officer, infiltrated dozens of protest groups including anti-racist campaigners and anarchists, a Guardian investigation reveals.
Legal documents suggest Kennedy's activities went beyond those of a passive spy, prompting activists to ask whether his role in organising and helping to fund protests meant he turned into an agent provocateur.
Kennedy first adopted the fake identity Mark Stone in 2003, pretending to be a professional climber, in order to disrupt the UK's peaceful movement to combat climate change. Then aged 33, he grew long hair and sported earrings and tattoos, before going on to attend almost every major demonstration in the UK up to the G20 protests in London. He was issued with a fake passport and driving licence.
