To manage such a broad remit, the Inquiry has divided its fact-finding work into six “tranches”. Special Demonstration Squad officers and managers and those affected by their deployments are split into three tranches each covering a different time period: Tranche 1: 1968-1982; Tranche 2: 1983-1992; Tranche 3: 1993-2007.

As a smaller and more recent policing unit, National Public Order Intelligence Unit officers and managers and those affected by their deployments are the focus of a single tranche – Tranche 4.

Tranches 5 and 6 cover “Other undercover policing officers and managers and those affected by deployments” and “Management & oversight by mid- and senior-rank officers, other agencies and government departments” respectively.

The Inquiry intends to hold hearings in line with these tranches and in roughly chronological order.
