However, the case of Koloane is relatively simple. He said he was responsible for the Guptas landing a plane at the Waterkloof Air Force base. And after that fact, Zuma appointed him as an ambassador.
The evidence from Koloane in this was so weak that it might make Zuma particularly vulnerable.
This would make questions being put to Zuma on this issue particularly important, partly because of their simple directness. Imagine the scene:
Paul Pretorius: “Why, Mr Zuma, did you appoint Mr Koloane an ambassador despite his wrongdoing in this case?”
JZ: “Because he had a good track record as a diplomat.”
PP: “Had any other diplomat in the service ever done such a thing, opened a military base to a foreign plane in this way?”
JZ: “No”.
PP: “And why did you make this appointment?”
It would be a moment that could reveal much about Zuma.
