Bulelani T Ngcuka (pronounced [ɓulelaːni ŋǀʱuːkʼa]; born 2 May 1954) was the first national Director of Public Prosecutions in South Africa, and is the husband of former Deputy President of South Africa Phumzile Mlambo-Ngcuka. He was embroiled in controversy concerning the decision to prosecute Jacob Zuma for corruption; Zuma was later elected President of South Africa. Supporters of Zuma alleged that the decision to prosecute was intended to prevent Zuma from challenging Thabo Mbeki for leadership of the African National Congress. Among the accusations made against Ngucka by supporters of Zuma were that he was an apartheid spy.
Bulelani Ngcuka, one of five siblings, was born in Middledrift, Eastern Cape and schooled in the former Bantustan of Transkei. He obtained his B.Proc at the University of Fort Hare in 1977 and went to work for the Durban law firm of Griffiths Mxenge as an articled clerk in 1978. He finished his articles at GM Mxenge Law Firm in 1981, the same year Mxenge was assassinated by apartheid hit men. He spent eight months in solitary confinement in 1981 and was jailed for three years in 1982 for refusing to give evidence in the political trial of Patrick Maqubele and others. While in prison, he completed his LLB through University of South Africa (Unisa).
When Ngcuka was released in 1985, he left for Switzerland and worked at the equality of human rights branch of International Labour Organisation in Geneva for two years. It was here that he married Phumzile Mlambo. They have a son, Luyolo.
