Corruption watchdog Transparency International has warned that SA could be in breach of the African Union (AU) convention by allowing political parties to keep the sources of their private sector donations secret. Nongovernmental organisations have criticised government for not addressing this in the soon-to-be enacted Prevention and Combating of Corrupt Activities Bill as it leaves the door open for business to buy political influence without anyone being aware of this relationship. SA's major political parties are set to clash with the Institute for Democracy in SA (Idasa) in court later this year contesting Idasa's demand that they disclose the identity of private sector donors.
