JOHANNESBURG (Reuters) - South Africa's COSATU trade union federation threatened on Tuesday to pull out of an alliance with the ANC if the ruling party persists with disciplinary charges against union leader Zwelinzima Vavi.
"If the decision is allowed to stand it will create a terrible precedent which would spell the end of the alliance," the Congress of South African Trade Unions (COSATU) said in a statement.
The African National Congress (ANC) decided on Monday to discipline COSATU's leader Vavi for saying the union federation was concerned that senior ANC members were exploiting political connections to get rich.
COSATU is in a formal alliance with the ANC and Vavi is believed to be lining up a bid to head the party, which elects a new leader in two years' time.
The relationship between the ANC and its labour and communist party alliance partners has soured, threatening to split the decades'-old partnership that freed South Africa from white minority rule.
