§ Mr. Sanders
To ask the Secretary of State for Defence if his Department operates a monitoring exercise of persistent inquirers for information. 
§ Mr. Spellar
We do not monitor inquiries in such an exercise centrally. We do, however, monitor correspondence from the public sent to Ministers to determine our performance in responding to it. Where a correspondent has persistently corresponded with the Department on a particular issue and has been given the fullest possible answer, several times, it is our practice to send a formal letter stating that no further purpose will be served by continuing the correspondence. This decision is taken by an official at Grade 7 level or above and in accordance with Exemption 9 of the Code of Practice on Access to Government Information: Voluminous or vexatious requests.
