 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.
