To ask the Secretary of State for the Home Department, with reference to her Department's corporate report, entitled Animals in Science Regulation Unit Annual Report 2024, published in December 2025, whether she has made an assessment of the adequacy of the sanction for the case where the mother was removed from cage and killed, resulting in unweaned pups starving to death; and what steps she is taking to prevent animals dying from starvation in facilities licensed under the Animals (Scientific Procedures) Act 1986 (3).

To ask the Secretary of State for the Home Department, with reference to the Animals in Science Regulation Unit Annual Report 2024, published in December 2025, what assessment she has made of the implications for her policies of the incident in which mice were left without water for up to five days; whether she has considered the adequacy of a letter of reprimand being issued as a sanction in response; and what steps her Department is taking to prevent animals from being left without food or water.

All licensed establishments must fully uphold the required standards for animal welfare as set out in the Animals (Scientific Procedures) Act 1986 (ASPA) and the Code of Practice for the Housing and Care of Animals Bred, Supplied or Used for Scientific Purposes. The Animals in Science Regulation Unit (ASRU) conducts audits to assure establishments’ compliance and takes matters of non-compliance very seriously. All cases of non-compliance are thoroughly investigated. Where there is sufficient evidence for a breach, ASRU will issue a suitable and proportionate remedy to prevent recurrence of similar breaches. Moreover, ASRU’s Annual Report 2024 draws key learnings from cases of non-compliance and makes recommendations to reduce the risk of future non-compliance.

Regarding the incidents referenced, ASRU investigated the incidents and acted according to the published compliance framework (www.gov.uk/guidance/animal-testing-and-research-compliance-with-aspa) which explains how ASRU identifies and investigates potential incidents of non-compliance and decides on appropriate and proportionate measures and remedies.

The Government remains fully committed to continuous improvement in the regulation of the use of animals in science, and to strengthening the UK’s position as a global leader in science and innovation. As part of this, the Home Office is in the final stages of delivering a comprehensive programme of regulatory reform to further strengthen ASRU, ensuring confidence in the regulatory system and maintaining robust compliance with ASPA.

As part of the reform programme, the number of inspectors will increase from 14.5 full-time equivalent (FTE) positions at the end of 2017 to 22 FTE positions by March 2026.
