U.N. Secretary-General Ban Ki-moon, speaking to Zambia's parliament at the start of a visit Friday, called corruption a cancer that threatens democracy and anti-poverty efforts.
He says, "In this fight there can be no sacred cows, there can be no parallel systems of justice -- one for the poor and the weak; another for the powerful and protected."
Zambian President Michael Sata came to power in the southern African nation last year on an anti-corruption campaign. Ban is scheduled to meet Sata Saturday.
