>> South Africa is in battle President Jacob Zuma can now add one of his own party members to a long list of opponents attempting to move the vote of no confidence. The break in ranks revealing the depth of anger awaiting him when parliament decides his fate in three weeks.
Reuters Sub-Saharan bureau chief Ed Cropley is in Johannesburg where a coalition of Zuma's critics are in conference.>> Behind me you can see lots and lots of delegate's. There are representatives from the church, from Muslim organizations, from unions, academia, opposition political parties. And indeed some dissident MPs from Zuma's African National Congress.
And one of the most powerful speeches we heard just now is from dissident AMC MP. Who has come out very, very strongly saying that Zuma is a disgrace to the African National Congress and indeed to South Africa. He's really rationizing politics he's even introducing a tribal element to politics.
Which is something that South Africa hasn't seen since before the end of apartheid in 1994.>> Eight years in office and this is the ninth time Zuma's faced a threat like this. His tenure's been marked by an economic downturn and scandal including using $16 million in state money to fund what was built as a security upgrade to his home, but included things like a new chicken coop.
He paid back a small fraction. His associates have also been accused of corruption.>> July 18 is Nelson Mandela's birthday, and it's the day on which South Africans are urged to think about their community spirit, think about giving back. To wider society and indeed the country. And so to have a conference like this, on a day like this, with a message like this, does indeed send a very, very powerful message.
>> Unlike past votes, this new one may be done by a secret ballot. If 50 of his party's 249 members side against him, he'll be shown the door.
