Kodwa said the ANC and its alliance partners were inspired by Ramaphosa's leadership and said the president had "earned his stripes as a leader of our glorious movement".
He implied that Lekota's attack on Ramaphosa's character was an election gimmick.
"Those who have nothing to offer to the people of SA will always find a way to throw stones and make attempts at denigrating his strong character," Kodwa explained.
The ANC in turn accused Lekota of "betraying an organisation that shaped his politics and career" for his utterances against Ramaphosa.
"Some of these people, who were trusted comrades and rose to the highest ranks of the ANC, have never hesitated to betray this legacy and trust when it suited their personal ambitions.
"Terror Lekota is one of those who had no qualms in betraying an organisation that shaped his politics and career over many decades for expediency," Kodwa added.
