The decision to prosecute African National Congress (ANC) president Jacob Zuma was not Leonard McCarthy's decision, the former South African Scorpions boss wrote in a letter, excerpts of which were published in The Star on Wednesday.
According to McCarthy, acting prosecutions boss Mokotedi Mpshe and Scorpions investigating director Thanda Mngwengwe were responsible for the decision.
Addressed to Mpshe, the letter, dated April 2, reads in part: "As you know, in the final analysis, the decision about whether to charge, on what counts and when, were taken by you and Adv. Mngwengwe."
The letter was written in response to questions put to him by the National Prosecuting Authority (NPA) on his alleged collusion in Zuma's prosecution, reported The Star.
Announcing the NPA's decision to drop charges against Zuma on Monday, Mpshe blamed McCarthy and former NPA head Bulelani Ngcuka for "manipulating the prosecutorial process".
According to excerpts of transcripts of telephone conversations read by Mpshe at Monday's press conference, McCarthy and Ngcuka discussed whether to charge Zuma before or after the ANC's Polokwane conference in December 2007.
Mngwengwe recently stated in an interview with the Sunday Times that: "I stand by my decision (to prosecute Zuma) until and unless the NDPP (Mpshe) decides otherwise".
