MI5 Admits Lying to Courts in Neo-Nazi Spy Case

The British security service, MI5, has for the first time accepted that it provided evidence based on lies to three courts and that senior officers were repeatedly dishonest. The admission was announced by Timothy Otty KC, representing MI5, during a High Court hearing in London on Friday.

A panel of three senior judges, including the Chief Justice of England and Wales, Baroness Sue Carr, is currently deliberating on potential actions, which could include unprecedented contempt of court proceedings against MI5 or individual officers.

This development follows a critical report published in July by the then deputy investigatory powers commissioner, Sir John Goldring. The report found that MI5 provided evidence based on "lies" while defending a neo-Nazi informant whose abuse was exposed by the BBC. Sir John's investigation was ordered by the prime minister in September 2025 after the High Court rejected MI5's initial explanations as unreliable.

MI5 "accepts without reservation" Sir John's findings, including those regarding individual officers' actions and "systemic failure" within the organization, Otty stated in court. Previously, MI5 had only issued apologies for providing "incorrect" evidence. Otty added that MI5 "fully accepts and acknowledges the gravity of the issues raised" and committed to a significant reform program under Director General Sir Ken McCallum, emphasizing that such failures must not recur.

Otty argued against contempt of court proceedings, suggesting they would not be in the public interest given the thorough Goldring investigation, MI5's apologies, and its reform commitments. He noted that one officer, known as Officer 2, has resigned, while another, Officer 3, has been suspended and faces disciplinary action that could lead to dismissal.

The case centers on an MI5 informant, referred to as Agent X, described as a foreign neo-Nazi and misogynist who allegedly used his role as a tool for abuse, including coercively controlling his partner, referred to as Beth, and attacking her. MI5 reportedly assisted him in traveling abroad for intelligence work while he was under police investigation.

In 2022, the government attempted unsuccessfully to block a BBC investigation into Agent X, leading to the informant being granted legal anonymity. Beth subsequently sued MI5 at the Investigatory Powers Tribunal, and in 2024, she sought a High Court review of a ruling. MI5 maintained a "neither confirm nor deny" policy (NCND) in court, arguing for secrecy and preventing disclosure of Agent X's status, which the courts accepted. This stance placed Beth at a significant disadvantage.

However, MI5 had, in fact, disclosed Agent X's agent status in phone calls to the BBC journalist investigating the case in 2020, in an attempt to dissuade the investigation. Officer 2 allegedly falsely claimed Agent X was not abusive, misogynistic, or a genuine extremist. When the BBC presented evidence, including a recording of a call with Officer 2, MI5's claims of maintaining the NCND policy were challenged.

Following the BBC's revelations, initial official inquiries concluded that the false evidence stemmed from mistakes and poor memory, absolving MI5 officers of deliberate wrongdoing. However, a panel of senior High Court judges in July 2025 ruled these inquiries suffered from "serious procedural deficiencies" and their conclusions could not be relied upon, leading to Sir John's investigation and the current High Court hearing.
