Orgreave campaigners are to hold a 'justice' conference in Sheffield this weekend.
Members of the Orgreave Truth and Justice Campaign - who have been calling for an independent inquiry into police actions at the infamous Battle of Orgreave in 1984 - have arranged the event at the Quaker Meeting House on St James Street this Saturday.
The event will run between 10am and 4pm and be chaired by Sheila Coleman from the Hillsborough Justice Campaign.
A spokesman for the event said: "This conference organised by the Orgreave Truth and Justice Campaign (OTJC) is being held as an opportunity to learn from a range of campaigns for justice who are challenging and resisting the role played by the state in undermining the right to organise collectively for social justice and workers rights.
"It will also be an opportunity to share ideas and information for future action."
Among the speakers will be Henrietta Hill QC, who is legal counsel for the Orgreave campaign, as well as Roy Bentham from the Blacklisting Support Group and Helen Steel from Police Spies Out of Our Lives Campaign.
There will also be representatives from the 'Rotherham 12' campaign, a group which is fighting against the prosecutions of a group of Pakistani-heritage men alleged to have been involved in violent disorder after a Britain First demonstration in the town last year.
The bitter dispute at Orgreave in June 1984 during the Miners' Strike resulted in dozens of injuries on both sides as police and pickets clashed.
Pickets complained of excessive force by some of the 6,000 officers brought in for the strike.
South Yorkshire Police referred itself to the Independent Police Complaints Commission in 2012 over allegations officers colluded to write court statements about the clash.
The watchdog later said the passage of time prevented a formal investigation, but said there was 'support' for the allegation that senior police exaggerated pickets' use of violence.
