Personal data, mainly on MOD employees and their dependents, for which the Department is responsible are stored and processed in permanent and deployed units overseas, but within UK jurisdiction. Similar data are also held on overseas based and locally employed staff by Defence Attachés in British embassies. The volume of personal data held outside the Defence overseas footprint is not currently held centrally. As part of the departmental response to the Cabinet Office-led Review into data handling procedures in Government, an internal review is currently establishing a more comprehensive assessment of personal data held and accessed overseas.
