President Thabo Mbeki has issued a stern warning that corruption will not be tolerated among members of his cabinet and the executive structures in provincial and local government. Mbeki says the government will have to ensure that the work of its executive structures - national ministers, provincial premiers and provincial ministers as well as mayors and members of their executives - "is not undermined or compromised by corruption". Mbeki's comments come amid intense scrutiny of Deputy President Jacob Zuma's financial adviser, Schabir Shaik, who is on trial in the Durban High Court, facing fraud and corruption charges for allegedly soliciting a bribe from French arms company Thales. Zuma has not been charged and denies any wrongdoing.
