There is a similar principle, i.e a vote of no confidence, but there is no equivalence whatsoever between the two situations so its a very poor comparison to make. Zuma is a corrupt criminal. Zille is guilty of poor judgment in calling a spade a spade. Okay then,  lets vote against her just to show the others how its done.

As far as corruption in the WC I am sure it exists but nothing like the scale it does in ANC run provinces . Its worth remembering the unqualified or almost unqualified audits received by Cape Town year after year. If you have information that Zille is corrupt, then lets hear it.
