Johannesburg - The DA said the announcement by ANC MP Makhosi Khoza that she was quitting the ruling party was proof that the party was unable "to self-correct".
Khoza quit the African National Congress (ANC) on Thursday, leaving the ruling party with this parting shot: "Goodbye new alien and corrupt ANC, I quit."
Outspoken Khoza, who was facing disciplinary action from the KwaZulu-Natal ANC for refusing to bow to instructions to not talk out against the President, said the party she joined at the age of 12 in 1982 was a far cry from the current ANC which she said protects corruption.
"I have decided that I will no longer tap dance with the deadly, greedy hyenas and wolves. I have come to realise that decolonising, reconstructing, reconfiguring, reconciling, and growing South Africa cannot be pursued on an amoral and immoral platform," she said addressing journalists at the Liliesleaf farm in Johannesburg.
She has denied that she intends to join any opposition parties.
The DA in a statement said it noted her decision to quit the ruling party.
"Her decision to leave the ruling party is further proof, form one of its own members, that the ANC cannot self-correct.
"It is clear corruption has compromised the ability of the ANC to govern in the best interest of the people of South Africa," the party added.
ANC spokesperson Zizi Kodwa meanwhile, said the party had not received Khoza's resignation letter.
Speaking to eNCA, Kodwa said because Khoza joined the movement at the branch, and not at a press conference, she should have submitted her letter to her branch or at least the ANC caucus in Parliament.
