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.
Jeremy Corbyn said he was "appalled" that the Government have ruled out an inquiry into Orgreave.
In a tweet, the Labour leader said the decision announced by the Home Secretary on Monday afternoon denied "truth and justice for victims and their families."
Yvette Cooper, chairwoman of the Home Affairs Select Committee, urged Mrs Rudd to reconsider her decision.
She told MPs in the Commons that 95 miners faced the injustice of being charged, while some "went through very difficult trials based on charges and evidence that later collapsed".
She added: "Given her predecessor's record of a whole series of inquiries and reviews in cases where injustice was suspected, would she think again about her decision today?"
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.
