ITV News understands the details of more than 100 Britons, including spies and special forces, were included in the data leak that resulted in thousands of Afghans being secretly relocated to the UK.
Details of MI6 spies, SAS and special forces personnel were included in the spreadsheet, after they had endorsed Afghans who had applied to be brought to the UK.
Asked about the leak of British personnel’s information, an MoD spokesperson said: “It’s longstanding policy of successive governments to not comment on Special Forces.
"We take the security of our personnel very seriously and personnel, particularly those in sensitive positions, always have appropriate measures in place to protect their security.”
