Overview

The Tranche 3 Phase 1 hearings of the Undercover Policing Inquiry took place from 13 October 2024 to 17 December 2025 at the International Dispute Resolution Centre in central London. It began with three days of opening statements, heard from 13 to 15 October, with witness evidence beginning on 17 October.

Undercovers who gave evidence included HN16 James Thomson 'James Straven',  HN43 Peter Francis 'Pete Black'  and HN15 Mark Jenner 'Mark Cassidy'.

Undercovers HN26 Christine Green,  HN66 'Dave Jones'  and HN60 'Dave Evans'  were not called by the Inquiry. Nor was HN81 'Dave Hagan', who was apparently too ill to attend. This led to complaints from a number of core participants who submitted that he ought to be summoned to give evidence, and a procedural hearing in relation to this on 3 November 2025. One manager, HN143 Dennis 'Ben' Gunn,  a holdover from Tranche 2, did give evidence, though the hearing for his fellow manager, HN587 Peter Phelan, was cancelled due to ill health.

Due to the prominence of some of the undercovers and the gravity of the accusations against them, much of their evidence took several days each. There was also vital testimony from a number of campaigners in relation to them, including women deceived into relationships. The targeting of justice campaigns, particularly that of Stephen Lawrence, received considerable attention as well. Another notable issue was Operation Lime , a supposed gun-smuggling plot involving James Thomson. These hearings are the only ones in which a former spouse of an undercover officer has given evidence to date: this is 'S', the ex-wife of Mark Jenner.

The hearings also included multiple Restricted Reporting Orders (RROs)  to protect sensitive information about witnesses from wider dissemination. As a result, several hearings were not broadcast and were heard only by those who attended in person. For others, only audio evidence was broadcast.
