HN25 is the cipher given to a former Special Demonstration Squad undercover who was deployed in the late 1980s / early 1990s against a group which no longer exists. Their cover name is due to be released by the Undercover Policing Inquiry, when it was revealed he used the name Kevin Douglas to infiltrate the Troops Out Movement from 1987 to 1991. The Chair of the Undercover Policing Inquiry, Sir John Mitting, has ruled that his real name will be restricted in that Inquiry.

In the Undercover Policing Inquiry
- 7 March 2018: the Inquiry Chair, John Mitting, wrote he was minded to restrict real name of HN25 but would refuse application over the cover name, saying there was no real risk to HN25 from the target group, and there existed a strong sterile corridor between real and cover names. Investigation of the group was necessary to fulfil the Inquiry's terms of reference. Mitting also noted that there was also a particular reason exists as to why there might be impact on HN25's private and family life, which justified the restriction on publishing HN25's real name.
- 11 Jan 2018: Inquiry directed that any restriction orders applications for HN25 were to be submitted by end of Jan 2018.
- 13 September 2018: An open application will be published to allow responses to the Chair 'minded to' decision to restrict real name.
