Families of the 22 people murdered in the Manchester Arena terror attack have accused MI5 of “significant failings” and told the security services, “Do not fail us again”.

A statement from loved ones of the bystanders who died in the suicide bombing by Salman Abedi in 2017 was read out after two days of evidence by a senior MI5 officer, identified only as witness J, to the public inquiry into the attack.
