Dali Mpofu Senior Council for the mineworkers, said during the public hearings in July, that Ramaphosa, a Lonmin shareholder, used former police minister Nathi Mthethwa to exert political pressure on the police to act against the protesting Marikana miners.
"You were the intermediary, the conduit, through which the pressure Mr Ramaphosa refers to was conveyed to the senior management of police and ultimately to the officers who killed people," Mpofu said while cross-examining Mthethwa at the inquiry at the time.
Mpofu read out an e-mail from Ramaphosa, as a Lonmin shareholder, to fellow board members: "I have just had a discussion with Susan Shabangu [then minister of mining]. She agrees that [what] we are going through is not a labour dispute but a criminal act.
"She will correct her characterisation of what we are experiencing. She is going into cabinet and will brief the president as well and get Police Minister Nathi Mthethwa to act in a pointed way. Let us [apply] the pressure on them to act correctly."
The commission is investigating the deaths of 44 people during strike-related violence at Lonmin's platinum mining operations at Marikana in August 2012.
