Home secretary Theresa May has announced a new police investigation into the Hillsborough disaster.
It comes after Attorney General Dominic Grieve asked the High Court to quash the original inquest verdicts into the 1989 disaster.
Former Durham Chief Constable Jon Stoddart is to lead the new police inquiry, which will focus specifically on the 96 deaths of Liverpool fans.
He will not be allowed to employ any officers with a connection to the disaster to work on the inquiry.
The Liverpool supporters died in a crush at Sheffield Wednesday's Hillsborough stadium on April 15 1989 where their team were to meet Nottingham Forest in an FA Cup semi-final.
Ms May said: "I am determined to see a swift and thorough response to the findings of the Hillsborough Panel to deliver justice for the 96 football fans who died and the families who have fought so hard on their behalf."
Mr Stoddart said: "I am aware of the great significance and personal responsibility which comes with leading this criminal investigation.
"My first priority is to meet with as many of the families as possible and to establish a working open relationship with them throughout the investigation."
Meanwhile, a packed High Court this morning heard the Attorney General's application to overturn the Hillsborough inquest verdicts.
Many families of victims of the tragedy had travelled to the Royal Courts of Justice to hear Dominic Grieve state his case before the Lord Chief Justice, Lord Judge and two other judges.
Many others watched proceedings via video link up at a court in Liverpool.
