Bosses 'aware' of police spy relationship Police have admitted for the first time that an undercover officer had a sexual relationship with an environmental activist with the knowledge of bosses. Legal documents seen by the BBC reveal they knew about Mark Kennedy's relationship with Kate Wilson and allowed it to continue. She was among several women he had relationships with while undercover. In public statements to date, police maintained such relationships would never have been sanctioned. Posing as an environmental campaigner, Mark Stone, the police spy began a two-year relationship with Ms Wilson in 2003. She was one of a number of women he was involved with during his seven years undercover. In his real life Mark Kennedy was married with children. Its very poor. I hope that the victims get some justice and that those responsible are punished.
