Mr Radebe is the longest "serving" and also lowest achieving minister we have ever had. This is the first time he has actually done anything at all, except perhaps to breathe. Despite this, he has made a fortune mainly by marrying it (no doubt he is heading for a swift kick in the vitals at home, as his wife is a termagent of note). 

Whether he dissappears or continues to achieve nothing has no effect on anything except that he is another drain on the ficus.
