It is the policy of HM Treasury and OGC not to release data concerning fewer than five staff where to do so could lead to the identification of protected personal information about individual members of staff. Since 1999, I can confirm that the information requested relates to fewer than five cases. Information for earlier years could be obtained only at disproportionate cost.
Under the Data Protection Act 1998, DMO would not record this information. Any supporting documentation is destroyed after six months due to the Data Protection Act.
