HN341 is the cypher for a former Metropolitan Police Special Branch officer who worked with the Special Demonstration Squad (SDS) in the late 1970s and early 1980s. Neither his real nor his cover name has been published. He gave evidence in a closed session to the UCPI.
Details concerning his deployment, target groups, and operational activities have not been published to protect HN341's identity. This only leaves HN341’s recollection of the SDS’s work culture and his reflections on his daily life as an undercover.
The details published are contained in a heavily censored transcript of HN341's closed hearing, which is the source of the article below, unless stated otherwise.
SDS work, HN341 said, was distinct from that of mainstream Special Branch squads. SDS officers immersed themselves among target groups and monitored activists’ lives in detail.
HN341 said gathering public order intelligence was ‘my primary function’:
I know for a fact that I was able to give a lot of valuable intelligence back to Uniform Branch, me and my superior officers, about certain forthcoming events and demonstrations. Even if they never materialised, at least they had prior warning of it.
The usefulness of SDS intelligence in this regard has been called into question by the evidence presented at the Inquiry.
HN341 also emphasised that sustaining his undercover identity was his principal concern during deployment.
As with other undercovers, HN341 confirmed that he used a cover name, address, and documentation and developed a back-story, though he was seldom questioned by those he was spying on about personal details. He added that SDS work was the ‘antithesis’ of normal Special Branch duties:
in the sense that, whereas your routine Special Branch work focused on detail and information, the SDS work focused more on social interaction.
However, the type of information he reported was much the same, except it was:
in a lot more detail. They [the SDS] were far more interested in movements of people…attending at one meeting and disappearing for a couple of months and coming back again.
Describing his daily routine, HN341 said the SDS safe house served as the unit’s meeting place. Officers attended twice weekly.
Meetings involved communal discussions about deployments, forthcoming demonstrations, personalities within target groups and operational developments. Managers and undercover officers generally remained together in the same room throughout these discussions.
According to HN341, if particularly sensitive matters arose, they were usually discussed discreetly in the same environment rather than in formal private meetings, unless they became serious enough to require discussion at Scotland Yard.
SDS work culture
HN341 described the SDS as a ‘tightly knit’ unit whose members relied heavily upon one another for support. He stated that officers trusted one another implicitly and often formed close friendships that lasted beyond their deployments.
He said undercover officers would often go out to meals or drinks together after safe-house meetings and occasionally organise informal gatherings or barbecues involving spouses and families. Senior officers generally avoided attending these social occasions because their appearance and demeanour would have appeared conspicuous alongside undercover officers with long hair and beards.
Officers often discussed the stresses associated with undercover work, including the pressures on marriages, maintaining cover identities, and living double lives. HN341 described the atmosphere within the SDS as one where ‘banter’, anecdotes and jokes were common; operational matters were generally avoided during purely social gatherings.
According to HN341, emotional support within the SDS came primarily from fellow undercover officers rather than from management.
Welfare
HN341 also described the severe stress associated with long-term undercover work. He said that heavy drinking and chain-smoking became methods of coping with the pressures of deployment, functioning both to maintain cover and as a form of self-medication. However, he said the level of alcohol intake, although high, was not that much out of the ordinary within the police as a whole.
He went on to say that his SDS deployment placed a serious strain upon his private life and contributed to the breakdown of his relationship. HN341 stated that he had received no warning from the SDS before joining about the likely emotional consequences for family life.
According to HN341, SDS management provided practical assistance regarding expenses, promotions and operational matters, but emotional support was ‘non-existent’. He said there was no counselling, no formal debriefing and no psychological support after deployment.
Stress meant that HN341 eventually asked to leave the SDS, citing his increasing and overwhelming sense of paranoia.
HN341 also described a culture of workplace cynicism. He said officers would not expect praise or any acknowledgement for the stressful work. He added that professionals in other walks of life, whom he later spoke to, were shocked by the lack of support for SDS officers, although MI5 officers he spoke to shared similar experiences.
HN341 stated in his evidence that he did not engage in sexual relationships while undercover.
He also claimed that he never heard about colleagues having sexual relationships with activists, even though it is now established that such sexual relationships were commonplace. He said such conduct ‘would have been off limits’ and stated that having sex with activists would not have entered his head because of the risks associated with compromising cover identities.
He also stated that management never explicitly discussed sexual relationships with undercover officers, but he believed the operational and security risks alone made such conduct unthinkable.
Inquiry Chair Sir John Mitting, in his Minded-to note, stated that he believed that HN341’s deployment was dangerous and that if either the real or cover name was revealed, there would be a risk of harm. In March 2018, therefore, Mitting decided to restrict both the real and cover names.
