THE Metropolitan Police have finally admitted that a notorious spycop’s managers knew he deceived a woman into an intimate relationship and did not stop it, legal documents have revealed.

As an officer in the National Public Order Intelligence Unit, Mr Kennedy – using the name Mark Stone – infiltrated dozens of groups in a seven-year stint, during which time he duped environmental activist Kate Wilson into a two-year sexual relationship.

Now, for the first time, police chiefs have confessed to knowing that Mr Kennedy’s “cover officers and line manager” acquiesced in his sexual relationship with Ms Wilson.
