“He should resign because of the manner in which he stood by whilst these structures were put up,” Bizos told eNCA in an interview on Thursday.

“He could not possibly have been ignorant of what was happening.”

Bizos said Zuma had been inconsistent in his statements as to what knowledge he had or what monies may have been spent and what was the nature of it.

“Those are morally incorrect,” he said.

The calls for Zuma to resign have increased following the Constitutional Court’s ruling that he had failed to uphold the Constitution when he did not comply with Public Protector Thuli Madonsela’s remedial action regarding payment for the non-security upgrades to his Nkandla homestead.

The call has come from opposition parties, civil society, some ANC members and party veterans such as Ahmed Kathrada, former finance minister Trevor Manuel, former ANC deputy secretary general, Cheryl Carolus and uMkhonto weSizwe veteran, Mavuso Msimang.
