Cape Town -

A joint technical committee will manage the integration of the DA and Agang SA structures and volunteers, DA leader Helen Zille said on Tuesday.

“This is a game-changing moment for South Africa,” she told reporters in Cape Town.

Zille said that when she was elected Democratic Alliance leader in 2007, she set out a case for the realignment of politics in the country.

“I said then that political change will come about as the old political formations become obsolete. We can see this happening now.”

Zille announced earlier that Agang SA leader Mamphela Ramphele would be the DA's presidential candidate in the upcoming general elections.

She said the DA's leadership was drawn from across the political spectrum but they shared the same values, “the belief in an open-opportunity society for all characterised by non-racialism, a market economy, human rights and prosperity for every South African”.

Zille said talks between Agang SA and the DA have been going on “continuously”.

“The truth is we have been interacting continuously... you look at different formats, you go through different options...

“We have an agreement politically, we just need the technical details worked out,” Zille said.

Zille said former president Nelson Mandela's death had changed many things for South Africa.

Ramphele added: “I am the bridge between my generation who fought for freedom and the new generation which now needs to lead.

“The ANC is fracturing along all the broad-church lines,” said Ramphele.

Ramphele said even ANC supporters wanted political change.

“Good people in the ANC have reached out to us, but are scared,” she told reporters in Cape Town.

“Good business leaders have reached out to us but are nervous.”

Ramphele said millions of people wanted to make a different choice in this year's election.

“This is your government-in-waiting.

“I will not lead you, not lead us, nor lead South Africa on the path of conflict but of commitment - to you, to your children, to health, to high quality education and job opportunities,” Ramphele said, flanked by Zille. - Sapa
