Question to the Department of Health and Social Care:

To ask His Majesty's Government what technical controls are in place in the UK Biobank Research Analysis Platform to monitor and restrict the download of participant-level data, and how long they have been in place.

UK Biobank is a charity and operationally independent of government. The Government has been working closely with UK Biobank in its response to the data breach which it reported to the Government on 20 April 2026. Measures taken so far have included the suspension of access to their research analysis platform, revocation of access permissions from the institutions involved, rapid removal of the listings from the e-commerce platform, self‑referral to the Information Commissioners Office, and urgent work to introduce technical barriers to prevent download of participant‑level data.
