A new political party, the Workers and Socialist Party (Wasp) will be unveiled on Thursday.
The announcement would be made at press conference in Tshwane, Wasp spokesman Mamatlwe Sebei said in a statement on Wednesday.
He said it was fitting to launch the party on Human Rights Day.
"It reeks of utter hypocrisy for this government to organise events to celebrate Human Rights Day in the wake of Marikana," Sebei said.
