FORMER Land Bank managing director Helena Dolny is suing former chairman Bonile Jack for R650000 in a defamation suit. Business Day reports that the summons was expected to be delivered to his home by a deputy sheriff. In a letter to President Thabo Mbeki, Jack accused Dolny of racism, nepotism as well as mismanagement. The letter was leaked to The Star, which published the claims. Mbeki referred the memorandum to Land Affairs and Agriculture minister Thoko Didiza.
