The Crown Prosecution Service is to announce its decision later on whether individuals and organisations will face criminal charges over the Hillsborough disaster.

Relatives of the victims will attend a meeting with the CPS where the decisions would be revealed.

The disaster took place at the 1989 FA Cup semi-final which killed 96 football fans.

New inquests which concluded last year found the victims were unlawfully killed and fans were not to blame.

In January Hillsborough investigators passed files relating to 23 suspects to the CPS to decide whether charges should be brought.

This came as a result of two separate criminal investigations by the Independent Police Complaints Commission and Operation Resolve, which was set up in 2012 by then Home Secretary Theresa May.

Fifteen of the suspects relate to the probe into the causes of the disaster, while eight relate to the IPCC inquiry into the conduct of both South Yorkshire Police and West Midlands Police.

The Operation Resolve investigation looked at the preparation for the match and events of the day.

The former chief superintendent of South Yorkshire police David Duckenfield gave evidence at the Hillsborough inquest and testified that it was his decision to open a gate at the crowded turnstile that led to the fatal crush.

Since December Crown prosecutors have been deliberating whether he should face criminal prosecution.

ITV News understands it is not the decision to open the gate 28 years ago that will be the basis of any criminal case but the lack of preparation for the events that that led to that decision and the failure to respond to the tragedy that immediately unfolded.

Margaret Aspinall, chairwoman of the Hillsborough Family Support Group, said: "It's been a long, long struggle for everybody and hopefully this is the journey to the end, completely, of Hillsborough.

"We've got to wait with anticipation to see what happens."

Mrs Aspinall, whose son James was aged 18 when he died in the tragedy at the Sheffield Wednesday ground, said families would have a "sleepless night" ahead of the decisions.

"It is going to be a day of mixed emotions for the families and we have had so many of them.

"Whatever happens, I still think it will be a long road, but the families are determined to never give up.

"All we want is accountability, nothing more and nothing less."
