Kgalema Motlanthe has rejected as unnecessary calls for an investigation of the arms deal, which increasingly threatens to undermine the ANC even further at a time when the ruling party needs all the help it can get. It seems certain that between the work of the Scorpions, the investigations of the media, and probes from other parties, not to mention trials of the accused, the full story will eventually emerge. It might be best for Motlanthe, Jacob Zuma, and the ANC to champion openness and take what damage might be coming to it rather than to add a lack of transparency and attempts to obfuscate or cover up corruption.
