Archbishop Desmond Tutu and former South African president FW de Klerk have written to President Kgalema Motlanthe requesting that he set up an independent commission of inquiry to investigate the arms deal that has so shaped and warped the current South African political climate. It is hard to imagine what rationale Motlanthe or the ANC might use to refuse such a request, which, of course, says nothing about whether or not the requested inquiry will happen.
