In an unprecedented admission, the Security Service apologises for “inaccurate” evidence.

Summary

MI5 admitted to lying to three courts to defend its handling of “Agent X,” a violent neo-Nazi informant who attacked his girlfriend with a machete.

The agency falsely claimed it never confirmed informants’ identities, despite previously disclosing X’s status to a BBC journalist.

MI5 issued an “unreserved apology,” but the revelations raise concerns about its transparency and credibility in legal proceedings.

The Home Secretary has ordered an independent review, while MI5 faces internal disciplinary actions. The case will return to court to reassess MI5’s role in failing to protect the victim.
