Recommendation MAI-39: Single consolidated GMP Operation Plato plan
From Manchester Arena Inquiry: Volume 2: Emergency Response, published 3 November 2022.
Recommendation
Greater Manchester Police should review its Operation Plato plans to ensure that there is only a single plan to which all can work and that this plan gives clear and consistent guidance on how to respond to an Operation Plato incident.
In brief (written by this site)
In February 2026, Greater Manchester Police reported via the Cabinet Office dashboard that the recommendation was completed, stating that its Operation Plato Marauding Terrorist Attack Overall Plan is the only plan that exists within the force (Cabinet Office, Feb 2026). The force noted that this plan incorporates role cards providing clear guidance during an incident and that strict version control prevents responders from accessing superseded versions (Cabinet Office, Feb 2026). The UK Government had previously recorded the recommendation as accepted in full in November 2025 (Cabinet Office response, Nov 2025).
