David Conn, who has written extensively about Hillsborough, has written this piece about what we can expect today.

Here is an extract from the story:

The families of the 96 people who died in the Hillsborough disaster will receive a report on Wednesday intended to establish the truth about what happened that day and in the aftermath, based on an examination of thousands of official papers.

David Cameron will make a statement in the House of Commons on the report, expected at about 12.30pm after prime minister's questions. He has been urged by the families and Merseyside Labour MPs to deliver an apology over failures that caused the disaster, and over the attempt by South Yorkshire police to shift blame on to Liverpool supporters.

The report by the Hillsborough independent panel, established three years ago and chaired by the bishop of Liverpool, James Jones, will be accompanied by the publication later on Wednesday of 400,000 official documents from 80 organisations. The families of victims will be shown the documents before they are publicly released.

The families have for 23 years held a burning sense of injustice that those who died at the FA Cup semi-final between Liverpool and Nottingham Forest on 15 April 1989 were failed by the legal processes that followed.

Today, government papers about the Hillsborough disaster that have remained hidden from the public eye will be released. They are expected to shed more light on what happened on the 15 April 1989, when 96 Liverpool fans died in a crush on the terraces of Sheffield Wednesday’s ground during a FA Cup semi-final between Liverpool and Nottingham Forest.

The Hillsborough Independent Panel has scrutinised 400,000 pages of documents for the past 18 months and will issue its report today, with victim’s families being given first access at Liverpool’s Anglican cathedral.

With your help, we will be analysing the report and the data as it becomes available. Our reporters David Conn, Owen Gibson and Andy Hunter will be in Liverpool today – you can follow then them on twitter @david_conn, @owen_g and @AHunterGuardian.
