Manchester Arena bombing
UK Home Secretary Priti Patel announces the inquests into the deaths of the victims will be converted into a public inquiry at the request of the coroner. This enables the hearing of evidence in secret by members of the intelligence community, which would otherwise not be available as the coroner had previously granted public interest immunity to the witnesses on the grounds of possible assistance to future terrorists were the evidence to be heard. Inquests cannot hear secret evidence.
