Campaigners have repeated their calls for an inquiry into one of the most violent episodes of the miners strike in the 1980s.
Police and miners clashed at a coke plant in Orgreave, near Rotherham, in 1984.
Heavy-handed policing was blamed by miners, although police claim they were defending themselves.
Former miners, trade unionists and campaigners attended an annual march and rally in Orgreave on Saturday.
A public inquiry into the incident was ruled out by the home secretary in October.
