In South Vietnam, a referendum was scheduled for 23 October 1955 to determine the future direction of the south, in which the people would choose Diệm or Bảo Đại as the leader of South Vietnam. During the election, Diệm's brother Ngô Đình Nhu and the Cần Lao Party supplied Diệm's electoral base in organizing and supervising the elections, especially the propaganda campaign for destroying Bảo Đại's reputation. Supporters of Bảo Đại were not allowed to campaign, and were physically attacked by Nhu's workers. Official results showed 98.2 per cent of voters favoured Diệm, an implausibly high result that was condemned as fraudulent. The total number of votes far exceeded the number of registered voters by over 380,000, further evidence that the referendum was heavily rigged. For example, only 450,000 voters were registered in Saigon, but 605,025 were said to have voted for Diệm.
