Consider this scenario: Its 2019 and we have a new president. One that we wanted. We fought a hard campaign, formed a government of national unity that is "anti corruption". predictably a call for a"no confidence" vote is called by disgruntled majority-less MP's. In the background, we still have dodgy billionaire businessmen, who profit from destabilisation, uncertainty, policy delay and drawn out commissions of enquiry. What's a few hundred millions rands, in paper bags, doled out to MP's worth? Secret ballot anyone? Suddenly Bob's your uncle, your president (and his ministers) are recalled and there is NO recourse, no idea WHO was bribed, who folded, buckled, who has a swiss bank account. If you represent the people in parliament, then your vote should be public. If you are too scared to, then you need to resign and let someone else take your place. After all, if you are scared of fires, you don't become a fireman.
