Polokwane is not Mangaung – Vavi.

Cosatu General Secretary said they will not pronounce on leadership like they did at the 2007 ANC conference.

JOHANNESBURG - Congress of South African Trade Unions (Cosatu) General Secretary Zwelinzima Vavi on Thursday said the trade union federation's active involvement in electing the ANC president in Polokwane in 2007, is not necessary at the Mangaung conference in December.

Vavi said the only way to ensure unity within the tripartite alliance is to support the current ANC leadership.

This follows the ruling party's call urging the trade union federation not to pronounce on who it prefers to lead, ahead of the elective conference.

He said that decision was by the Cosatu Central Executive Committee held this week and that he respects that stance.

"I can't go out and say this is what I stand for and then still say I'm the general secretary.

"We did the intervention in 2007 based on a set of political circumstances and those do not exist in 2012."
