The Manchester Arena Inquiry published its third and final volume of findings following an inquest into the deaths of 22 victims on 22 May 2017.
After months of hearings, chairman of the inquiry Sir John Saunders found serious failings in the preperation and response to the attack.
The third volume – which was released on Thursday – detailed that the intelligence services missed a significant opportunity that might have prevented the attack.
He said: “There was a realistic possibility that actionable intelligence could have been obtained which might have led to action preventing the attack.”
The report also criticised the way information was shared about the Abedi brothers between MI5 and Counter-Terrorism Policing.
Priti Patel announced that there would be an independent inquiry in October 2019.
Due to Covid-19 restrictions, hearings within the inquest were paused or delayed at various points over two years.
Last week, the Inquiry came to a close almost six years since the bombing.
More than 1,000 documents were examined and 267 witnesses gave evidence.
Here is how the Manchester Arena Inquiry reached its conclusion:
