MI5 lied about relations with neo-Nazi informant, watchdog says

Review of case criticises handling of agent X, who exploited role with agency to violently threaten his girlfriend

MI5 has been reprimanded by a watchdog for lying about its relationship with a neo-Nazi informant, who had exploited his role with the spy agency to violently threaten his girlfriend.

The Investigatory Powers Commissioner’s Office (Ipco) criticised MI5’s handling of a man known only as agent X, and said some of its officers had initially misled the courts and the regulator about his true status.
