South Africa: ANC split is 'good for democracy'

The leader of South Africa's official opposition, Helen Zille, says she would welcome a split in the ruling African National Congress (ANC) party. She was responding to former Defence Minister Mosiuoa Lekota's threat on Wednesday to form anew party. "We're seeing a non-racial alignment... on the basis of principles and that's a very good thing," she told the BBC.
