Does any political party in SA allow its members to speak out against party policy and remain as members? The DA recently disciplined Helen Zille for doing just this. But for her grovelling apology she would have been kicked out. Isn't it the same thing in theory with Dr Khoza?However well meaning she may be. In America senators and congressmen can vote how they like without fear of being removed from office. And we've just seen that happen. But in SA, I wonder why we actually bother to have a parliament.
