Home Affairs Minister Malusi Gigaba tendered his resignation on Tuesday less than two weeks after the public protector found he had violated the Constitution and Executive Ethics Code by lying under oath.
The presidency confirmed Gigaba had handed in his resignation letter.
The finding by the public protector related to his decision to overturn the approval for the Oppenheimer-owned Fireblade Aviation to operate a private customs and immigration service at OR Tambo International Airport in Johannesburg.
The finding came after a high court in February this year found that he had lied under oath and violated the Constitution by reneging on the approval.
Just last week, Gigaba defended his actions, insisting he would not resign, but has now done an about-turn.
The minister, whose resignation comes into effect on Wednesday, also made headlines recently after he tweeted that he was being blackmailed after someone hacked into his phone and leaked a sex tape meant for his wife.
All manner of jokes and ridicule were thrown at him as the leaked tape went viral and landed on porn websites. - ANA
