Campaigners are holding a commemoration event to mark the 31st anniversary of the Battle of Orgreave.
Martin Fisher reports from the rally:
Members of the Orgreave Truth and Justice Campaign will gather at the site, with speakers including Yorkshire National Union of Miners president Chris Skidmore.
It comes a week after the police watchdog concluded that South Yorkshire Police won't be investigated over its handling of violent clashes between miners and officers at Orgreave coking plant in 1984.
Other speakers at the event include Kevin Horne, one of the miners who was arrested at Orgreave, and the new Labour MP for Sheffield Heeley, Louise Haigh.
Representatives of the Hillsborough Justice Campaign and Unite the Union are also expected to attend the public rally.
Campaigners are calling for a full public inquiry into the so called "Battle of Orgreave" more than 30 years ago. They claim police used excessive force against pickets during the height of the miners' strike - and also gave false evidence in court.
South Yorkshire Police referred themselves to the Independent Police Complaints Commission over the claims which were made more than two years ago. But the IPCC say because miners who were arrested were later cleared they are not pursuing their inquires. And that has angered those who say the truth has yet to come out. Chris Kiddey reports.
A North East MP has criticised a decision by the Police Complaints Commission not to investigate alleged misconduct by officers against picketing miners during the 1984 miners strike.
Labour MP Dave Anderson, who represents Blaydon in Gateshead, used to work as a miner.
He says he was present at the Orgreave plant in Rotherham in Yorkshire where it is alleged officers used "excessive force".
But following a two-year analysis of thousands of pages of documents related to the case, the IPCC said it had decided not to launch an investigation into the conduct of South Yorkshire Police.
Mr Anderson has described the decision as an establishment cover up by the 'forces of darkness'.
He said: "I'm not surprised by the outcome. It is yet another establishment cover up.
"Innocent people were stitched-up, beaten-up and set-up by the agents of the state and I have no doubt that this is the forces of darkness closing ranks to protect the powers that be that really run this country as opposed to us, who are democratically elected."
South Yorkshire Police Chief Constable David Crompton has released a statement about the police watchdog IPCC decision into the investigation of Orgreave.
Chief Constable David Crompton said: “For almost 31 years the actions of the police during the so-called Battle of Orgreave, and its pivotal role in the Miners strike, have divided opinion and created controversy.
“In October 2012, following a BBC documentary, there was renewed criticism of police actions. In the circumstances, I felt it would be inappropriate for South Yorkshire Police to act upon the criticisms by reviewing these events itself. I therefore took the decision that a variety of matters relating to police conduct at the Orgreave coking plant, on 18th June 1984, should be referred to the Independent Police Complaints Commission (IPCC) so that a fully independent assessment could take place regarding whether there had been either criminal conduct or disciplinary offences committed by police officers.
“I note the outcome of the in-depth review conducted by the IPCC which concludes that due to both the evidential and public interest considerations in this case there is no requirement for further investigation into these matters.
“Clearly, if any compelling new evidence comes to light regarding police conduct in the future, this is a decision which can be revisited.”
Campaigners have reiterated the need for a "Hillsborough-style inquiry" into South Yorkshire Police's handling of violence during the 1984 miners' strike after the police watchdog said it would not investigate alleged misconduct by officers.
The Orgreave Truth and Justice Campaign (OTJC) has issued the following statement:
Shadow home secretary Yvette Cooper has backed calls for an independent inquiry into Orgreave, after the IPCC said it would not investigate South Yorkshire Police.
"This decision lets down the Orgreave families and shows the weakness of the current system," she said.
"It has taken the IPCC two-and-a-half years to decide not to investigate the events at Orgreave and to conclude that the big questions weren't within their remit or resources. If they are too limited to do the job then someone else needs to.
"For too long there have been serious allegations about the way the miners were treated at Orgreave, but we have never had the truth. It's time for an independent inquiry, potentially modelled in the Hillsborough panel, to open up everything. It's time for the truth."
The Labour Leader Ed Miliband has called for what he calls a proper investigation into violent clashes between police and miners during the pit strike at Orgreave in South Yorkshire in 1984.
Mr Miliband's comments came during a speech to miners in his constituency. South Yorkshire police referred themselves to the Independent Police Complaints Commission in 2012 over allegations police officers had assaulted miners.
The IPCC says it is continuing with what it describes as a very complex process before deciding on future actions.
