The Prevention and Combating of Corruption Bureau (PCCB) is finalising investigations on ten corruption cases involving people who participated in Chama Cha Mapinduzi (CM) opinion polls recently. The PCCB boss, Dr Edward Hoseah, said the cases would be sent to court before the 31 October general election. Speaking during the 15th anniversary of the Legal and Human Rights Centre (LHRC) the PCCB executive director said the PCCB were waiting for more evidence so that legal action could be taken on other allegations.
