The devastating report which exposed the failures of the emergency services on the night of the Manchester Arena attack also highlighted how predictable that failure was.
Partly because of austerity cuts, Greater Manchester Police failed to keep up-to-date plans in place for major incidents and then, when a key training exercise revealed a key command position would become overwhelmed in the event of a real attack, they failed to learn lessons, Sir John Saunders' highly-critical report says.
GMP - and the other blue light services criticised in his report - following a long-running public inquiry, say they have updated their plans, enhanced training and improved communication between the blue light services, which almost totally failed in the first hour of the May 2017 attack, which claimed 22 lives.
