Undercover policeman seen posing as G8 activist in exclusive footage
Mark Kennedy formed relationships with protesters while he secretly gathered intelligence on them.
STV News has obtained video footage of a notorious undercover police officer posing as a protester during the G8 summit at Gleneagles in Perthshire in 2005.
Mark Kennedy spent eight years secretly gathering intelligence on activists and even forming relationships with some of them.
The Londoner infiltrated a number of protest groups between 2003 and 2010 before he was unmasked as a police mole.
On the day the G8 summit began, a group of activists were driven to Gleneagles in a minibus driven by Kennedy, who was calling himself Mark Stone.
He helped set up a protest camp in Stirling with activists who were completely unaware he was betraying their trust to pass information on to his superiors.
In her first broadcast interview, one of the women who fell in love with Kennedy told STV News she felt "violated" when she discovered who he really was.
Speaking to STV News from New Zealand, American protester Sarah Hampton said she was in a relationship with Kennedy during the summit. They went their separate ways in 2006.
"I would say that I had fallen in love with him, it was hard to get over," she told STV.
"It really felt like I was in some bad TV film. That feeling of anger – it'll probably dissolve over time, but it's never really going to go away.
"You were violated. And you were violated by an institution that you were supposed to be able to trust."
Kennedy resigned from the police shortly after being exposed. He went on to claim that after being unmasked he suffered from post-traumatic stress disorder.
A public inquiry into undercover policing is currently under way in England and Wales. The Home Office is considering whether or not Scotland should be included.
Police Scotland chief constable Phil Gormley has been dragged into the controversy. In 2006 he headed a division of the Metropolitan Police which was responsible for undercover operations. He has pledged to cooperate with the inquiry.
Earlier in January, one of the women who was deceived into a relationship with Kennedy won a High Court battle against Scotland Yard.
Kate Wilson, who was involved with the officer for two years, made claims against the force for deceit, assault and battery, misfeasance in public office and negligence.
The Metropolitan Police withdrew its defence in her case two months after seven other women who were tricked into relationships with Scotland Yard moles received an apology and substantial payouts from the force.
Ms Wilson said: "The police had already unequivocally accepted that the relationships were wrong. It is now clear that wrongdoing goes far beyond the individual undercover officers.
"Yet we are denied access to any information about the extent of the intrusion into our lives, who knew and how far up the hierarchy it went.
"The police's decision not to defend the claim is clearly motivated by a determination to avoid disclosure of documents relating to the undercover operations, at any cost.
"How many more women may have been affected by these abuses? How many more children may have been fathered by these undercover officers?
"It is clear the police are not going to come clean."
