In some cases the record may be no more than a name, but I am advised that for about 153,000 people who progressed as far as submitting an application form to join the forces, more extensive personal data are held, including passport details, national insurance numbers, driver's licence details, family details, doctors' addresses and national health service numbers; for about 3,700 people, banking details were also included.

Angus Robertson: To ask the Secretary of State for Defence how many of those individuals who had their personal details lost as a result of the theft in Edgbaston on 9 January of an MOD computer from the vehicle of a Royal Navy Officer are domiciled in (a) Scotland, (b) Wales, (c) Northern Ireland, (d) England and (e) elsewhere. 
Des Browne: Where a record of domicile is held, the following figures were recorded on the database at the time of the entry of the record.
Number Scotland 59,553 Wales 37,546 Northern Ireland 14,223 England 459,778 Elsewhere 34,667

This unencrypted data security breach could easily pit the lives of serving or former members of the armed forces, and their families, at risk from terrorists and foreign intelligence agencies. Even people who never actually joined the armed services, but just expressed an interest in doing so, could be at risk, especially if they have, say, easily identifiable Muslim names, or an address in an area that is familiar to fanatics.
