LIMPOPO - Deputy President, Cyril Ramaphosa is to address a Congress of South African Trade Unions (Cosatu) rally in Polokwane on Sunday.
Some analysts say Cosatu's endorsement of Ramaphosa to take over from President Jacob Zuma is in conflict with its own identity.
The trade union federation said Ramaphosa is the right person to lead the party into the 2019 general elections.
