The Christian Democratic Party called on President Jacob Zuma to resign on Monday, following a report that he had fathered a child out of wedlock.

"Mr President, please resign for the good of the country!" the party said in a statement.

This came after neither the ANC nor the presidency were prepared to comment on the report in the Sunday Times.

"Our country needs a leader acting as a moral compass, not a president imitating Tiger Woods, Bill Clinton and King Henry VIII all in one, and all for the wrong reasons."

Reverend Theunis Botha, leader of the CDP and acting chair of the Christian Democratic Alliance, said Zuma's justifying his polygamist unions as part of his Zulu culture was "an insult to the Zulus, as are his claims that his sexcapades are in line with his declaration of being a Christian".

"Whilst Zuma apparently finds enough time for a love life not matched by many, political analysts are increasingly claiming that Zuma is an absent president offering no leadership to the country.

"As we are leading up to the World Soccer Cup Tournament the eyes of the world are on South Africa, and the mockery of our presidency is the last thing we need."
