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.
Labour MPs reacted angrily to the Home Secretary Amber Rudd's decision not to hold an inquiry into the Battle of Orgreave.
Louise Haigh, MP for Sheffield Heeley, who first raised demands for an inquiry with then home secretary Theresa May in a 2015 letter signed by more than 100 Labour colleagues, said it was a "disgraceful betrayal of justice".
She said: "The Home Secretary today has put a screeching brake on the search for truth.
"For many communities in South Yorkshire the question of how police forces from across the country - not just South Yorkshire - which are supposed to be there to serve them could be used against them in such a brutal, deliberate way has left a bitter legacy. This decision will exacerbate that."
Senior backbencher and Leeds Central MP Hilary Benn said: "It's time the truth was told and the Government is failing in its responsibility by ruling out an inquiry."
Aberavon MP Stephen Kinnock branded Ms Rudd's decision an "absolute disgrace", while Barnsley MP Michael Dugher said it was "a complete betrayal of campaigners and a spit in the face for every former coalfield community".
Mr Dugher described the announcement as "a political decision to protect the interests of the Tory party".
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.
