The Civil Service Code, the Civil Service Management Code and Propriety Guidance on Government Communications, all provide guidance to staff on the publication of material relating to their official duties. Copies of each of these are in the libraries of the House. They are also available on the Cabinet Office website at:

Armed forces and MOD staff publishing material on the internet as part of their official duties, for example on the MOD's own website, are governed by a number of internal MOD documents including training manuals and style guides.
