The Chief Surveillance Commissioner, Sir Christopher Rose, publishes a yearly figure for property interference, intrusive surveillance and covert human intelligence sources for all police forces and other agencies, including HM Revenue and Customs (HMRC), in his annual report to Parliament. Sir Christopher does not break the figure into individual forces or agencies as the sensitivity of the information could lead to criminals assessing the covert capability of each force and agency. This applies equally to HMRC and it is therefore not considered to be in the public interest to make this information available.
