Undercover policeman married activist he was sent to spy on
Chief constable says relationships with targets in environmental movement 'grossly unprofessional'
Ex-wife of police spy tells how she fell in love and had children with him
Using the false identity "Jim Sutton", Boyling infiltrated Reclaim the Streets, an environmental group famed for bringing streets to a standstill in unruly protests against cars.
During his time undercover, when he is said to have become a key organiser, Boyling met a 28-year-old woman and began a relationship with her. He later disappeared from her life.
It was only when he reappeared a year later that he told the woman he was a police officer. They later married and had two children but divorced two years ago.
Speaking for the first time, the woman gave the Guardian a detailed account of their relationship and alleges that Boyling:
• Encouraged her to change her name by deed poll, apparently to conceal their relationship from his seniors at the Met. Her deed poll certificate is signed by Boyling, who lists his occupation as "police officer".
• Told her a ruling from seniors that undercover operatives should not have sex with targets was unrealistic, and developing relationships with activists was "a necessary tool in maintaining cover".
• Only informed a senior officer that he was in a relationship with an activist in 2005, around the time they married using her new identity.
• Named at least two other police officers who served as undercover operatives and indicated other political activists who he believed to be police officers.
Boyling and the Met were given a detailed account of the woman's allegations, but neither provided a response. The woman said tonight she hoped her story would reveal how deep infiltration of the protest movement "wrecks lives". "Everybody knows there are people in the movement who aren't who they say they are," she said. "Being too paranoid would hinder everything. But you don't expect the one person you trust most in the world not to exist." Senior officers say any suggestion they tacitly allowed operatives to have relationships are unjustified, and argue examples of inappropriate behaviour are rare.
The Guardian also today fully identifies two of the other undercover officers involved in spying on the eco-activists, previously called Officer A and B.
Their names and photographs were not used after representations from senior police, but both have now been extracted from undercover roles in other investigations, and they can be named as Lynn Watson and Mark Jacobs.
