John Vorster and Connie Mulder, the Minister of Information, were implicated in plans to use government resources to fight a propaganda war for the Apartheid government.
In 1973, John Vorster had agreed to Mulder's plan to shift about 64 million rand (£40 million) from the defence budget to a series of propaganda projects.
Vorster utilised bribes of international news agencies and purchase of the Washington Star Newspaper as part of the Muldergate Scandal.
As a result of his involvement in illegal state funding of propaganda projects, Vorster resigned as prime minister in 1978. He was succeeded by P.W Botha.
