PRETORIA, South Africa, July 26 (UPI) -- After leading a tough anti-corruption drive, South Africa's chief prosecutor, Bulelani Ngcuka, has handed in his letter of resignation.
The BBC reported Ngcuka's spokesman denied the allegation his boss had come under government pressure to stand down.
"It was not pressure, but it was in the interests of the organization," Sipho Ngwema, Ngcuka's spokesman, told the BBC. "For his personal growth, he has to look elsewhere, for other challenges."
Last year, Ngcuka said he had prima facie evidence to suspect Vice President Jacob Zuma's involvement in a corruption scandal, but did not have enough evidence to prosecute him.
