Kennedy says since he was unmasked he has been diagnosed as suffering from post-traumatic stress syndrome. His wife, Edel, has filed for divorce, and is seeking compensation for "emotional trauma".

"When my cover was blown it destroyed my life. I lost my job, my girlfriend and my reputation," he said. "I started self-harming and went to a shrink who diagnosed me with post-traumatic stress syndrome. The blame rests firmly at the feet of my superiors at the Met, who had a duty to protect me."

Ten women and a man are also suing the Met for emotional trauma, saying they were duped into having sex with undercover officers. Three of the women are former lovers of Kennedy. It is one of these women whom the ex-spy claims to have fallen in love with.
