The Undercover Policing Inquiry examines covert police deployments into political and campaigning groups. Its 2023 Tranche 1 interim report reconstructs the early Special Demonstration Squad through officers’ evidence and surviving reports. The record shows extensive collection of information about individuals and political organisation, beyond a simple account of impending public disorder.
An undercover report is not a transparent window into a group. It reflects the officer’s access, choices and the institution’s priorities. The inquiry can compare those reports with testimony from the people being observed and with the justification claimed for the deployment.
The report’s analysis of material from 1972 is revealing: hundreds of reports concern political activities and personal lives, while references to potential public-order issues form only part of the record. Some categories overlap. Treating every document as proof of a public-order threat would misread what was collected.

Where the evidence stops.
The inquiry’s stages cover different periods. A finding in an early tranche does not settle every later deployment or allegation. Claims about particular relationships or officers need their own evidence and findings.
