Tongaat, which said in April it would restate financial information after a formal review revealed certain accounting practices that needed to be re-examined, voluntarily suspended trading in its shares in Johannesburg and London in June.

"It has determined that the volume of trade over the past few years, together with the cost of maintaining the secondary listing, does not sufficiently warrant a presence on the LSE," the company said in a statement.

Tongaat said it would maintain its primary listing on the Johannesburg Stock Exchange. Shareholders as of Sept. 4 on the UK share register, a fraction of the total, will be transferred onto the South African share register, it added.
