Schabir Shaik, the man whose trial saw former deputy president Jacob Zuma implicated in fraud and corruption, declined to comment on Monday's decision to prosecute Zuma.
"No comment," Shaik said politely by telephone after the National Prosecuting Authority's announcement that Zuma would appear in court in Durban later this week to face corruption charges.
Earlier this month Durban High Court judge Hilary Squires read a verdict that found that the Zuma and Shaik had a "generally corrupt" relationship.
Shaik was Zuma's former financial adviser and a close friend from the struggle against apartheid.
Shaik has applied for leave to appeal his sentence of 15 years in prison.
Since then Zuma has been axed from his post by President Thabo Mbeki. - Sapa
