Last night Margaret Aspinall, who lost her son James in Sheffield, welcomed the growing momentum behind the disclosure.

She added: “We would like to get our hands on the files first, particularly as there could be medical statements about our loved ones.

“We want a truthful panel set up as we’ve had so many representatives who didn’t do their job properly in the first place, so we want to be extra vigil and careful.

“We’ll have a committee meeting soon to discuss this properly and decide how to go forward.

“There is optimism that we are finally, after all these years, getting disclosure.”

A total of 96 Liverpool supporters died in a crush at Sheffield Wednesday’s Hillsborough stadium on April 15 1989 where their team was to meet Nottingham Forest in an FA Cup semi final.

The victims’ families have been fighting for further inquiries into the deaths.

They believe a Major Incident Plan was never initiated by South Yorkshire Police and fans at the Leppings Lane end were denied emergency medical attention.

The families also dispute the findings of the single inquest into all 96 deaths, which ruled the victims were all dead, or brain dead, by 3.15pm and which subsequently recorded a verdict of accidental death.
