A 2023 review revealed 11 serious public sector data breaches across UK government entities, including the Ministry of Defence (MoD), HMRC, Metropolitan Police, and benefits systems. Key failures involved uncontrolled ad-hoc downloads of sensitive data, misdirected emails (wrong recipients/failure to use BCC), and hidden personal data in released spreadsheets. High-profile leaks included: - 10,000 Police Service of Northern Ireland (PSNI) officers’ personal data (2023). - 18,700 Afghans who worked with British military, exposing them to Taliban retaliation and forcing UK relocation efforts. - 6,000 disability claimants’ data and victims of child sexual abuse records. The government admitted only 12 of 14 security recommendations were implemented, despite the review being completed 22 months prior. The Information Commissioner (John Edwards) and parliamentary committees criticized the delays, warning of systemic negligence in data handling, eroding public trust in digital governance. The breaches risked lives (Afghan collaborators), national security (MoD/PSNI leaks), and societal harm (vulnerable groups’ exposure).

'guidance, civil servant training, and digital infrastructure '
