The trade union is now on an aggressive campaign against against the incumbent president as well as dishing out serious threat to him.

The Congress of South African Trade Unions (Cosatu) has called for President Jacob Zuma to resign as it “no longer believe in his leadership abilities”.

The federation says it doesn’t believe that the president is the right person to unite and lead the movement.

Cosatu’s call comes after another ANC alliance partner the SACP made a similar call, saying they had lost confidence in the president.

The calls come after Zuma reshuffled his Cabinet, axing finance minister Pravin Gordhan and angering some ANC leaders.
