"The charges have been laid in terms of Section 32 (1) (b) of the National Prosecuting Authority Act, which reads: 'Subject to the Constitution and this act, no organ of state, and no member or employee of an organ of state nor any other person shall improperly interfere with, hinder or obstruct the prosecuting authority or any member thereof in the exercise, carrying our or performance of its, his or her powers, duties and functions'," De Lille said in a statement.

The charges were the same as those laid by De Lille against former Justice Minister Brigitte Mabandla.

The ID leader said her party had now done what the National Prosecuting Authority (NPA) should have done in the case against African National Congress president Jacob Zuma.

"... we also want to drive home the point that the issue of interference in the independence of the NPA is a completely separate matter from the substantive evidence against Zuma," De Lille said.

On Monday acting NPA head Mokotedi Mpshe laid blame for the collapse of the case against Zuma squarely at McCarthy's door, saying he felt personally betrayed by his former colleague.

Mpshe said McCarthy had abused the legal process against Zuma for "collateral and illicit purposes", and that his conduct "offends one's sense of justice".

Ngcuka and McCarthy were implicated in the "conspiracy" against Zuma aimed at securing their preferred candidate as president.

Should Mabandla, McCarthy and Ngcuka be found guilty, they could face hefty fines and a sentence of up to ten years.

Western Cape police could not immediately confirm that the charges had been laid, asking for a written query.

Meanwhile, the ID leader slammed comments by Zuma at a press briefing on Tuesday morning.

She said Zuma's saying the corruption charges against him were "political and manipulative" and that "there was never a case against" him proved he was either "ignorant" or "continuing with the ANC's misinformation campaign".

"Zuma must take note that the truth is that the NPA dropped charges in spite of its assertion a few weeks ago that it had 'a winnable case' and also in spite of the Louis Harmse judgement, which stated that 'a prosecution is not wrongful merely because it is brought for an improper purpose'," she said.

She noted the High Court in Durban had formally dropped the charges against Zuma but said this did not amount to an acquittal and the evidence amassed by the NPA had to be tested in court.

"Until then the huge cloud of suspicion hanging over Jacob Zuma's head will continue to grow," she said.

Zuma on Tuesday told a media briefing there was no cloud of corruption hanging over him.

"There is no cloud. There has been allegations against me and the State has not been able to put up the case. I have not been found guilty in a court of law," he said.
