A shocking chapter in Britain’s long‑running undercover policing scandal has resurfaced as a woman publicly revealed how she was deceived into a five‑year romantic relationship with an undercover officer — only discovering his true identity after years of lies and emotional manipulation. The case adds fresh attention to serious concerns about deep deceit by undercover police officers who formed intimate relationships with members of the public while concealing their real purpose.
The woman, identified only as Alison in testimony to a public inquiry, said she had believed she was in a genuine relationship with the man she knew as Mark — only to realise much later that he was actually Mark Jenner, a covert operative sent to infiltrate political campaigns in the 1990s. During their sustained time together, he wove an elaborate web of lies about his background and life story, eventually leaving Alison abruptly without explanation in 2000. She only uncovered the truth after years of her own detective work and scrutiny of records that revealed his true identity and role.
Testifying to the formal Spycops Inquiry, Alison described the “sadistic tendencies” she saw in the emotional manipulation she endured — characterising the deception as deeply traumatizing and exploitative. She had shared large parts of her life with him: domestic routines, social events, holidays and personal family moments — all taken under false pretences. Unknown to her at the time, the officer was married to someone else and had children, facts he never disclosed as part of his cover.
The broader scandal involves numerous undercover officers deployed by UK police over decades to surveil political protesters and activist groups. Many of these operatives, including well‑known figures such as Mark Kennedy and Robert “Bob” Lambert, engaged in intimate relationships with women while undercover, concealing their true identities and purposes. Some officers even fathered children in those relationships without ever revealing their real background until they were exposed many years later.
At least 50 women are now known to have been deceived into long‑term relationships by undercover officers, prompting legal action and deep criticism of police practices. Critics argue that manipulating affection, trust and intimate relationships in this way constitutes a serious abuse of power that has left many victims struggling with emotional trauma, mistrust and long‑term psychological damage.
The Spycops Inquiry continues to examine the full extent of undercover policing abuses, including questions about supervision, institutional oversight and whether such deceptive tactics should ever have been permitted. For victims like Alison, the case is not just an isolated personal betrayal but a stark symbol of how deeply intrusive state operations can disrupt people’s lives under the guise of security and intelligence gathering.
