Charity chief resigns over gems

The former chief of a Nelson Mandela charity is resigning from its board after the revelation that he secretly kept diamonds passed on to him by supermodel Naomi Campbell.

Jeremy Ractliffe said he kept the stones in a safe for 13 years until he handed them over to South African police earlier this month.

This was after Campbell told the war crimes trial of the former Liberian president Charles Taylor that she handed them as a donation to Ractliffe after she was given them by two unidentified men after a 1997 charity dinner.

The prosecution says they were "blood diamonds" from Taylor. Prosecutors called Campbell to help prove that Taylor traded in illegal diamonds to arm Sierra Leone rebels. Taylor was also an architect of Liberia's civil wars.

The Nelson Mandela Children's Fund said Ractliffe would leave its board this month.

In a statement, the charity said Ractliffe regretted not having informed other officials about receiving the three uncut diamonds earlier, "and acknowledges that had he done so, he and the board could have found a better and lawful way to manage the situation."

It added Ractliffe had apologised "for the anxiety and possible reputational risk his conduct may have caused."

The fund said he would not seek re-election in a board vote scheduled later this month.
