graft body has no powers to prosecute which are vested in the office of the attorney general. The allegations of corruption in the central bank are the latest to rock President Mwai Kibaki's government whose image has suffered badly after three senior ministers resigned over graft. The finance, energy and education ministers resigned last month after their names were linked to two graft scandals in which millions of state funds were corruptly paid out. Mullei, who has strongly rejected recent pressure by manufacturers and exporters to intervene in the currency market to weaken the strong Kenya shilling, has previously faced allegations of wrongdoing over a banknotes printing tender. He denied any wrongdoing over the tender which was later awarded to Britain's De La Rue Currency. Mullei was appointed by Kibaki in March 2003. As the governor, he enjoys security of tenure. Under Kenyan laws, the governor can be sacked if convicted of dishonesty or fraud or upon the recommendations of a tribunal appointed by the president to investigate him.
