Overview
- Counter Terrorism Policing London ran a large live‑play exercise at Canary Wharf on Sunday that organisers describe as the largest of its kind in modern times.
- More than 1,000 participants took part, including police, counter‑terrorism investigators, firefighters, paramedics and Canary Wharf Group security plus dozens of actors who simulated casualties.
- The scenario practised a marauding terrorist attack and was not sparked by specific intelligence, though officials reminded the public the national threat level remains 'severe'.
- The drill incorporated lessons from past incidents such as 10‑second triage from the Manchester Arena response and trialled emerging tools including drones while a section of the estate was closed for live play.
- Officials said the exercise produced immediate multi‑agency learning, reinforced public–private cooperation and followed recent funding increases for intelligence and counter‑terror policing that aim to boost readiness.
