Today, the Home Secretary announced a new police investigation into the Hillsborough disaster.
It means the ambulance service, Sheffield City Council, the FA and Sheffield Wednesday could, once again, be put under the microscope.
The Hillsborough inquest verdicts of accidental death have been quashed by the High Court and a new police investigation has been announced.
Families of the Hillsborough victims are on their way to London for a historic hearing. They hope to hear the inquest verdicts overturned.
The police watchdog has begun consulting families for its independent investigation into the aftermath of the Hillsborough tragedy.
