The Manchester Arena Inquiry has now concluded. The closure notice from the Inquiry Chairman is available here.

The Manchester Arena Inquiry is an independent public inquiry, established on 22 October 2019 by the Home Secretary.  The purpose of the Manchester Arena Inquiry is to explore the circumstances leading up to and surrounding the terror attack on 22 May 2017. 

Sir John Saunders, having acted as the Coroner responsible for conducting the Manchester Arena Inquests, was appointed to Chair the Inquiry on 22 October 2019. Sir John, a former High Court judge, is responsible for discharging the Inquiry’s terms of reference and supervising its progress. He cannot make any findings of civil or criminal liability. He has published his findings and recommendations across three report volumes here.

In September 2019 Sir John Saunders requested that the Home Secretary convert the Manchester Arena Inquests into a public inquiry. This request followed a number of pre-inquest hearings, culminating with a Public Interest Immunity Hearing on 6 September 2019. On 13 September the Coroner issued a ruling that upheld the substantive Public Interest Immunity applications. It was following this ruling that the Coroner, Sir John Saunders, now Chairman of the Inquiry, requested that the Inquests become a public Inquiry.

In his letter to the Home Secretary, Sir John Saunders set out the following: “It is of vital public importance that an Article 2 compliant investigation that is full, fair and fearless is conducted into the terrible events that resulted in the deaths of the 22 people killed at the Arena. I have reached the view that, in light of my ruling on the Public Interest Immunity applications […] such an investigation cannot now be achieved through the inquests and must be done by establishing a statutory public inquiry”.

In a ruling dated 11 April 2023, Sir John confirmed that, following the Inquiry’s extensive investigations, the 22 Inquests would not be resumed. The ruling is available here. More information of the Inquests, the hearings that took place during 2018 and 2019 and documents relating to the Inquests process can be found here.

A public inquiry is set up to look at a matter of public concern and is fully independent of Government. Unlike proceedings in court, an inquiry is not adversarial. It is an inquisitorial process instead. The focus of an inquiry is first to determine exactly what happened and then to work out what must be done to prevent it from happening again. Though inquiries cannot determine criminal or civil liability, they can highlight where failings have occurred. 

A Public Inquiry is set up to look at a matter of public concern.

The way an Inquiry is run may look and feel like a court case – a judge, representatives asking questions, bundles of evidence – but there is an important difference.

Courts often deal with cases by trials, involving one or more parties against another. There is usually a winner and a loser. For that reason it is called an adversarial process. An Inquiry is different to a court case. It is inquisitorial instead: all parties are there to examine the facts and to find out exactly what happened. An Inquiry will also make recommendations to try to prevent what has gone wrong from happening again. It therefore serves a wider public interest.

How do Statutory Inquiries work?

  • Statutory public inquiries run according to the rules in the Inquiries Act 2005 and Inquiry Rules 2006.
  • Inquiries are always established by a Government minister but once established are independent of Government. Inquiries must be fearless in looking for the truth and make findings of fact. If appropriate these will include identifying those at fault; however, the law does not allow an Inquiry to make findings of criminal or civil liability.
  • Inquiries always have a chairman, often a judge, appointed by the minister. Any person or organisation can be made to produce relevant documents. It is a criminal offence to intentionally withhold a document required by the Inquiry or deliberately to obstruct its work. Inquiries enable people with a particular interest to be Core Participants. They have certain rights.
  • All relevant evidence will be shared in advance of hearings with Core Participants.
  • Core Participants can suggest lines of questioning that should be pursued by the Inquiry.
  • Inquiries hold hearings and any person or relevant organisation can be called as a witness to give evidence.
  • Witnesses can be asked questions by Counsel to the Inquiry or by legal representatives of Core Participants (with the Chairman’s permission).
  • Inquiries are public. In general, the Chairman must take reasonable steps to ensure that the public can watch hearings and view the record of evidence. The Chairman must not depart from that rule unless there is very good reason.
  • Inquiries must produce a written report with their findings and recommendations. Under the Act, this must be made public.

The Manchester Arena Inquiry has been established under the Inquiries Act 2005. Other inquiries established under the Act include the Infected Blood Inquiry, the Leveson Inquiry and the Grenfell Tower Public Inquiry as well as the E Coli Inquiry in Wales and the ICL Inquiry held jointly between Scotland and England. Such inquiries are essentially inquisitorial in nature and, subject to the legislative provisions, their procedure and conduct are matters for the Chairman to decide. As such, no two inquiries are the same. The Inquiry is charged with carrying out an investigation within its terms of reference.

The Manchester Arena Inquiry was established by the Home Secretary on 22 October 2019. Hearings started on 7 September 2020 and concluded on 7 June 2023. A series of preliminary hearings took place before the start of the evidence hearings.

The Inquiry’s Terms of Reference can be found here.

The hearings were held at Manchester Magistrates’ Court, Crown Square, Greater Manchester, M60 1PR. Anyone wishing to watch the hearings can do so via the Inquiry’s YouTube channel.

On each day of hearings, the transcript and evidence considered will be published on the Inquiry’s website unless any contrary order or restriction order made under section 19 of the Inquiries Act 2005 is in place. Directions, submissions and rulings will also be made available, when appropriate.

The Inquiry operated with limited attendance due to Covid-19 restrictions and so it was not possible for members of the public to attend in person. Anyone who would like to follow proceedings could do so in a variety of ways:

  • The Inquiry provided a video feed of each day’s proceedings on its Youtube channel, and you find this here.
  • Transcripts of the day’s proceedings were published on the Manchester Arena Inquiry website each day, alongside evidence shown in the hearings.
  • The Inquiry published updates and information on its social media feeds on twitter @mcrinquiry

Support is available for anyone affected by the attack throughout the inquiry. For a list of organisations visit the support page of our website: here

All hearings will be open to the public and media unless a restriction order, made under section 19 of the Inquiries Act 2005, is in place. Closed hearings are not available to the public. The Inquiry’s closed hearings were held in November 2021.

Under Rule 5 of the Inquiry Rules 2006 core participants can include individuals, organisations or entities with a significant interest in an important aspect of the matters to which the Inquiry relates.  Those designated as core participants, by the Chairman, may participate in the Inquiry in a number of ways including making an opening and closing statement at certain hearings and suggesting lines of questioning to be pursued by Counsel to the Inquiry. A list of the Inquiry’s Core Participants can be found here.

A witness is someone who has evidence relating to the matters being investigated by the Inquiry. This could be as a witness to an event or through the records they hold (videos, photographs or documents). Witnesses may be called to give evidence in the form of a written or oral statement. An individual or organisation can be both a core participant and a witness. 

Under the Inquiries Act 2005, the Chairman has a wide range of powers, including the power to compel the production of documents and to summon witnesses to give evidence on oath. The Chairman can call any relevant person, or organisation, to give evidence to the Inquiry. Witnesses can be asked questioned by Counsel to the Inquiry or by legal representatives of core participants (with the Chairman’s permission).

An expert witness is a person who is called to give an opinion on matters which call for expert skill and knowledge. Their role is to provide technical analysis and expertise in order to help the Inquiry deliver its Terms of Reference. The Chairman appointed a range of experts to prepare reports and give oral evidence at the hearings.

Under the Inquiries Act 2005, the report must be made public. The Chairman has published his report in three volumes:

Volume 1, published on 17 June 2021, addresses the security arrangements at the Arena. Volume 1 can be found here.

Volume 2, published on 3 November 2022, addresses the emergency response to the Attack. Volume 2 can be found here.

Volume 3 (open), published on 2 March 2023, addresses the issues of radicalisation and preventability. Volume 3 (open) can be found here. Volume 3-I (closed) was published on 2 March 2023 and Volume 3-II (closed) was published on 7 June 2023. The closed report is not publicly available.

The Inquiry is not covered by the Freedom of Information Act, but will endeavour to conduct proceedings as openly and transparently as possible. As part of this, as much information as possible will be provided on this website.
