South Africa’s leading political party, the African National Congress, lashed out at US President Donald Trump over the denigrating remarks he was alleged to have made about Nelson Mandela, former South African president and civil rights leader.

A recent book published by Michael Cohen, titled ‘Disloyal: A Memoir,’ had said that Trump accused Mandela of ruining South Africa after his death in 2013.

“All freedom-loving people of the world are appalled by these insults, which come from a person who himself is not a model of competent leadership,” the party said, condemning Trump’ remarks. They also labelled the US President as the most “divisive, misogynistic and disrespectful person” ever to serve as US president.

“We do not believe that leaders who conduct themselves in the way Mr Trump does are in a position to offer authoritative commentary on the life and work of Madiba,” said the Nelson Mandela Foundation.

“Mandela fucked the whole country up. Now it’s a shithole. Fuck Mandela. He was no leader,” Trump said at the time of Mandela’s death, Cohen wrote in the book.

Meanwhile, the White House has dismissed allegations raised by Cohen in the book, calling them the words of a “disgraced felon and disbarred lawyer and a liar” seeking to clear his own name.
