Question to the Home Office:

To ask the Secretary of State for the Home Department, if she will make an assessment of the potential implications for her policies of the findings of the report by the National Physical Laboratory, published on 4 December 2025, on the use of facial recognition technologies by the police.

The Government has already taken action to address the findings of the National Physical Laboratory’s report on the algorithm used for retrospective facial recognition within the Police National Database.

The Home Office commissioned the report as the provider of the system, to enable police forces as the users of the system to assure themselves that they were meeting their Public Sector Equality Duty, specifically with respect to bias mitigation. The National Police Chiefs Council have led on this for policing by reviewing training and guidance. The Home Office has also commissioned His Majesty’s Inspectorate of Constabulary and Fire & Rescue Services (HMICFRS) to ensure these mitigations are consistent and robust.

Furthermore, a replacement system with a new algorithm has been procured and independently tested. This testing has been published and shows that the system can be used with no statistically significant bias. It is due to be operationally tested early next year and will be subject to further evaluation.

On 4 December 2025, we also started a public consultation that asks for views on a new legal framework for law enforcement use of facial recognition and other biometric technologies. The consultation includes questions on oversight arrangements and proposes creating a new regulatory and oversight body. We envisage this body would directly address issues such as potential bias in algorithms, potentially through powers, subject to legislation, to provide assurance that law enforcement use of biometric technologies is legal, responsible, and necessary.

Given the importance of this issue, we have also asked the HMICFRS, alongside the Forensic Science Regulator, to review law enforcement’s use of facial recognition. They will assess the effectiveness of the mitigations, which the National Police Chiefs Council supports.
