On the eve of the tabling of the long-awaited arms deal report, subpoenas against MP's from at least four political parties have been revoked.

The Speaker of Parliament raised concern about the implications the subpoenas would have for parliamentary privilege.

When the report is tabled tomorow, Frene Ginwala will make the unusual move of asking the chief investigators to report directly to MPs. The investigation into the deal is the largest ever in the new South Africa.

The government has apparently been cleared of any "improper or unlawful conduct" regarding the multi-billion rand arms deal.

Those cleared include the President and Cabinet Ministers.

The Auditor-General Shauket Fakie, the Public Protector Selby Baqwa, and the National Director of Public Prosecutions, Bulelani Ngcuka have been investigating corruption, conflict of interest and undue process in the purchase of new defence stock.

They say there are no grounds to suggest that government's contracting process was flawed and say their findings resulted from a lengthy criminal and forensic investigation.

Public hearings were also conducted.
