6 February 1979
Prime Minister P.W. Botha offered to resign amid speculation regarding his involvement in the Information Scandal of 1978, if his accusers could prove that either he, or a member of his Cabinet, was aware of activities relating to the Information Scandal. This followed after a motion was tabled in parliament by opposition parties. This came after disclosure that funds from the department of defence, of which Botha was the minister at the time, was used to fund covert operations. The Erasmus Commission cleared Botha of any guilt.
