Hundreds of survivors injured during the Manchester Arena attack and their relatives are suing MI5, it has been revealed.

More than 250 people have submitted their claim to the Investigatory Powers Tribunal (IPT) to take legal action against the country’s security service, it is being widely reported by multiple national news outlets this morning, including BBC News, Sky News, ITV News, and more.

The IPT investigates complaints about the alleged conduct of public bodies.

Their claim comes after an inquiry back in March 2023 concluded that MI5 missed a “significant opportunity” to prevent the attack, in which 22 people tragically lost their lives, and thousands more were left injured and affected, during and following a bombing at the end of an Ariana Grande concert at Manchester Arena on 22 May 2017.

According to the inquiry’s findings, a number of communication breakdowns between MI5 and Counter Terrorism Police North West officers meant that intelligence was not shared.


On top of this, the inquiry also found that two pieces of information about bomber Salman Abedi had been assessed by the security service at the time and concluded to not relate to terrorism.

Hudgell Solicitors, Slater and Gordon, and Broudie Jackson Canter are the three solicitor firms representing the group of 250 survivors and relatives.


“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 (IPT),” a statement on behalf of the three solicitors reads.

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

MI5 will also not be providing comment, due to ongoing legal proceedings.

Following the conclusion of the injury last March, MI5’s Director General, Ken McCallum, made a rare public statement saying he was “profoundly sorry that MI5 did not prevent the attack”.

His statement at the time read: “Having examined all the evidence, the chair of the inquiry has found that ‘there was a realistic possibility that actionable intelligence could have been obtained which might have led to actions preventing the attack.
