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.
Orgreave campaigners declared "justice has been denied, but the fight will carry on."
A spokesman told journalists outside the House of Commons: "The campaigners have worked tirelessly to place on the political agenda the urgent need for a public inquiry into key questions into the role of the police on that day.
"We are determined and the continue to build on the all ready wide."
Andy Burham, who stood with the campaigners, said that without knowing the truth about Orgreave, the Hillsborough relatives would continue to be denied the full story.
Throwing his weight behind the campaign, he said: "It's my firm view that we will never have the full truth about Hillsborough until we also have the truth about what happened five years earlier when the same police force used the same tactics to try and put the minors in a bad light in the same they later tried to and discredit Liverpool supporters."
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.
