(BBC) Police were told of shortcomings in a terror response plan months before the Manchester Arena attack, an inquiry has heard.
The police inspectorate warned in November 2016 that “an over-reliance” on the officer in charge of the response could see them overwhelmed.
Policing experts believe that is what happened after the May 2017 attack.
A former inspector told the inquiry Greater Manchester Police (GMP) was urged to “raise its game” at the time.
The public inquiry into the atrocity, which killed 22 people as they left an Ariana Grande concert, has been hearing about inspections of GMP around the time of the attack.
