The UK's security service, MI5, exhibited "serious failings" in its management of a covert agent, code-named X, who displayed "strong indications" of an interest in violence and was "openly misogynistic," according to a report by the security service's watchdog. The Investigatory Powers Commissioner's Office (IPCO) found that MI5 did not adequately review the agent's suitability despite evidence of concerning behavior.

IPCO concluded that video footage showing Agent X threatening his girlfriend with a machete should have prompted a review of his status as an agent, but it did not. The agency was aware that Agent X was involved in the "pick up artistry" movement, a subculture that teaches men how to exploit women for sex, and that he was "openly misogynistic" with his handlers. However, these aspects "did not attract much attention" from those managing him.

Furthermore, MI5 knew Agent X was "obsessed" with violence because he communicated this to them directly. The watchdog noted "indications he might be a threat to others arising from his general interest in extreme violence." Despite this, IPCO stated there was a "lack of sufficient professional curiosity" from MI5 regarding the agent's behavior and potential risks.

In response to IPCO's findings, a statement indicated that MI5 has since implemented "significant changes to its policies, practices and procedures." These changes have been subjected to subsequent inspections, and IPCO continues to supervise MI5's work in this area. The report highlights a failure within the security service to maintain adequate oversight of an agent whose behavior raised substantial red flags regarding his potential threat to others and his suitability for sensitive operations.
