A Ministry of Defence data breach that exposed the details of about 19,000 Afghans has now been linked to 49 deaths among family members and colleagues, with about 24,000 people still stranded in Afghanistan. For one Afghan interpreter in north London, the damage is still unfolding: his brother’s resettlement application has been rejected, is under appeal and his brother remains in Afghanistan.
The breach is back in focus because a June 7, 2026 report shows the fallout has not ended, even after the Ministry of Defence stopped in-country assistance for movements out of Afghanistan in April 2026. Eligible Afghans now have to reach a safe third country on their own before their cases can be processed, leaving families to solve a problem the government created with a single spreadsheet and then kept hidden for years.
That spreadsheet, emailed in February 2022 from UK Special Forces headquarters, contained names, contact details and case information for Afghans who had applied for protection under the Afghan Relocations and Assistance Policy. Once family members were included, it held 33,000 rows of data. The Ministry of Defence did not discover the breach until August 2023, when parts of the database appeared in a Facebook group, and then sought an unprecedented superinjunction that blocked reporting and kept Parliament’s Public Accounts Committee and the National Audit Office in the dark.
Victims were not told until July 2025, when the High Court lifted the injunction. By then, the scale of the harm was already coming into view. Research submitted to Parliament surveyed 350 Afghans, including 231 who had been formally notified that their data had been compromised. Among them, 200 said they had faced personal risks or threats to their family members, and Taliban forces had raided the homes of 105 respondents or their relatives.
The evidence also points to a breach that moved far beyond administrative embarrassment. Forty-nine respondents reported that a colleague or family member had been killed as a direct result. Sir Geoffrey Clifton-Brown said the department “knew what it was doing — it knew the risks of using inadequate systems to handle sensitive personal information as the security environment in Afghanistan deteriorated.” The Public Accounts Committee, in a report published in November 2025, said it did not have confidence in the ministry’s current ability to prevent a similar failure.
The Afghan Relocations and Assistance Policy was meant to protect people who had worked alongside British forces from Taliban reprisals. Instead, thousands whose names were exposed remain under Taliban rule, and those still hoping to leave now face a new barrier: finding a safe third country before their claims can even be processed. How many of the 24,000 left behind will make it out is still the question that matters most.
