Survivors of the Manchester Arena bombing have instigated legal action against MI5, it has been confirmed. Lawyers representing more than 250 people caught up in the atrocity at the Ariana Grande concert on May 22, 2017 say they have submitted a claim.

In a joint statement, Hudgell Solicitors, Slater & Gordon and Broudie Jackson Canter, the three lead firms representing the group said: "Legal teams representing injured survivors of the Manchester Arena bombing in 2017 can confirm that they have collectively submitted a group claim on behalf of more than 250 clients to the Investigatory Powers Tribunal.

“As it is an ongoing legal matter, we are unable or provide any further details, or comment further, at this stage.”

The Investigatory Powers Tribunal is an independent judicial body which provides right of redress to anyone who believes they have been the victim of unlawful action by a public authority using covert investigative techniques.
