Ramaphosa ignored a similar letter from Zuma two weeks ago, in which he challenged the president for accusing ANC cadres of corruption and urging them to be in the forefront of ending the vice.
This call, Zuma said, was not “genuine to the true character of the ANC” because Ramaphosa described the ruling party as “Accused Number One.”
Zuma’s latest letter was released on Wednesday as the ruling party started its National Executive Committee meeting in Pretoria.
In the letter, Zuma demanded that Ramaphosa should “come clean” about financial donations he used in the campaign to oust him from the ANC presidency in 2017.
Ramaphosa’s office has yet to respond to the former leader’s letter.
