The British government quietly relocated thousands of Afghan nationals to the United Kingdom after one of the country’s most serious data breaches exposed personal information of individuals who had worked alongside British forces, according to a report by Reuters.
The operation, initiated under the previous Conservative government, was launched out of fear that those affected by the breach could be targeted by the Taliban. By May 2025, the program had brought more than 16,000 people to the UK, many of them former interpreters, support staff and their families. The total cost is estimated at close to £2 billion.
The breach — described as one of the most damaging security failures in Britain’s recent history — included sensitive details about Afghan nationals who had applied for relocation through UK protection schemes. Some of the documents also contained references from British Members of Parliament and senior military officers who had vouched for the applicants.
“This serious data incident should never have happened,” said John Healey, Britain’s defense secretary, in remarks to the House of Commons. “While this occurred three years ago under a previous government, I want to offer a sincere apology to everyone whose information was compromised.”
Healey confirmed that approximately 4,500 Afghan nationals and their family members were either already resettled in the UK or en route under the confidential relocation scheme, which operated in parallel to existing programs. However, he added that no additional resettlement requests tied to the breach would be accepted, citing a government review that found limited evidence of systematic targeting by the Taliban.
The summary of that internal review, released Tuesday, acknowledged that the data exposure had placed thousands at potential risk but concluded that active Taliban retaliation had not been substantiated in most cases.
The disclosure comes at a politically sensitive moment for the UK, as the government faces budgetary constraints and growing pressure from right-wing parties, particularly Reform UK, which has gained ground in recent polls on an anti-immigration platform.
In addition to mounting political scrutiny, the government is now facing legal challenges from individuals affected by the breach. Shaun Humber, a solicitor with Leigh Day who has represented Afghan clients in previous security cases, said the exposed individuals “likely have strong claims for significant compensation” due to the distress and anxiety caused by the breach.
While many of those resettled were processed through existing relocation programs, the breach prompted an extraordinary and largely undisclosed policy shift, reflecting the scale of the risk and the potential consequences of administrative failure in times of crisis.
