Campaigners for an inquiry into the so-called 'Battle of Orgreave' have vowed to continue their fight.
Members of the Orgreave Truth and Justice Campaign told a news conference "we regard the gloves as off" in response to Home Secretary Amber Rudd's decision not to look further into violent clashes between miners and police in 1984.
The Home Secretary was accused of failing to fully review all the evidence over violent clashes between police and striking miners in Orgreave before deciding not to hold an official inquiry into the incident.
Andy Burnham said it was "staggering" that Amber Rudd had "brushed away" calls for an inquiry into the 1984 clashes.
He accused Ms Rudd, who was not present in the Commons to answer his question, of failing to obtain and examine original files held by South Yorkshire Police over the incident.
Her office may also have overseen "utterly cruel" treatment of campaigners after parliamentary sources initially indicated to reporters that an inquiry would go ahead, he said.
Brandon Lewis, speaking on behalf of the government, insisted that Ms Rudd had reviewed a wide range of documents and considered range of factors before reaching a decision.
"I fully appreciate we have a disagreement on this - it doesn't mean the Home Secretary's decision is wrong", he said.
Campaigners said "we regard the gloves as off" as they responded to the Home Secretary's decision not to hold an investigation.
In scenes reminiscent of the English Civil War, the Battle of Orgreave split the United Kingdom and changed industrial relations for ever.
The Government has chosen not to hold an inquiry into the conduct of South Yorkshire Police during the so-called Battle at Orgreave.
