What could happen to UK businesses affected by the scandal?
Through Mr Wiese's stakes in Steinhoff and Brait SE, a number of British firms may be exposed.
Shares in Brait SE have dipped in recent weeks, but not as sharply as Steinhoff's.
"I think these businesses stand on their own and trade reasonably robustly. The only impact has to do with [market] sentiment," says retail analyst Richard Hyman.
He adds: "Stock markets are not famous for their rationality. I'm not in any way saying this is a storm in a teacup. I'm saying this is something in a teapot and no-one knows quite sure what it is yet.
