Lekota was responding to calls by the Young Communist League for Mbeki to be charged for his alleged mishandling of the HIV/Aids issue during his term of office.
He said for a crime of genocide to be committed there must be a deliberate policy or decision to kill people. He said there was no such decision either by the ANC or Cabinet.
Lekota's statement comes just a week after youth leader Julius Malema said the ANC Youth League would not allow Mbeki to be charged with genocide.
"We must not charge one of our own. If we allow that, the same thing would happen to [Zimbabwean President Robert] Mugabe, and the same would happen to [President Jacob] Zuma, and the next thing you know they will come for you," Malema said.
