The attorney general is to apply to quash the original verdicts of "accidental death" in the inquest into the 96 Liverpool fans killed at Hillsborough.
Dominic Grieve QC is expected to announce to parliament on Tuesday that he is to apply to the high court to have the original verdicts overturned in the wake of new evidence revealed by the Hillsborough Independent Panel's report, which was published last month.
The report, which ran to 395 pages and was based on consideration of 450,000 pages of evidence, laid bare for the first time the full reasons for the disaster and the extent of the cover-up that followed as the police attempted to shift the blame.
It also revealed that up to 41 of the 96 victims had the "potential to survive" beyond the 3.15pm cut-off time imposed by the original coroner, prompting new questions over how many could have been saved had the emergency response been better.
Some families of the victims, who have campaigned on the issue for 23 years, have said that having the original inquest verdict quashed is their number one priority.
Grieve will answer questions raised by the report and provide a written statement to MPs "on his consideration of the issue", said a spokeswoman for his office.
It was clear there were "significant issues over the original inquest", Grieve said.
But he admitted the procedure "will take some time" and acknowledged "the wait for truth and justice has been long and unspeakably painful for a great many people".
If a new coroner is appointed, he is expected to liaise with the families over whether a new inquest should proceed ahead of any criminal or disciplinary charges that may arise.
On Friday, the Independent Police Complaints Commission announced it would launch the largest ever review of police conduct in light of new evidence unearthed by the panel.
Simultaneously, the director of public prosecutions, Keir Starmer, said he would undertake a review of all the evidence to see if new charges of manslaughter could be brought against corporations or individuals.
