The Facts

  • MI5 has issued an "unreserved apology" after admitting it provided false evidence to three courts while defending its handling of a neo-Nazi informant known as agent X who attacked his girlfriend with a machete.

  • The Security Service falsely claimed it maintained its policy of neither confirming nor denying (NCND) informants' identities, when in fact a senior MI5 officer had disclosed X's status to a BBC journalist while attempting to prevent investigation of the agent.

  • The false testimony was first given during a 2022 High Court case where the government sought to block BBC from reporting on agent X's wrongdoing, then repeated to the Investigatory Powers Tribunal where X's former partner "Beth" sought answers about MI5's handling of the agent.


The Spin

Narrative A

The public has a right to know about X's identity to protect women from a dangerous predator, and that MI5's attempts to suppress the story while knowing about his violent behavior demonstrate institutional failure to address domestic abuse. The evidence shows X used his MI5 status to coerce and terrorize his partner, and the service should have known it was inappropriate to use him as an informant.


Narrative B

MI5 plays a crucial role in protecting national security, often dealing with highly sensitive information. While providing incorrect evidence to the courts is a serious issue, we must recognize the extreme challenges faced by intelligence agencies. Mistakes happen in high-pressure environments, and what matters is MI5’s commitment to accountability, transparency, and correcting errors to maintain public trust.
