Among the original Free Officers, what did Nasser do to his opponents? 
Nasser's nomination for the post and the new constitution were put to public referendum on 23 June and each was approved by an overwhelming majority. A 350-member National Assembly was established, elections for which were held in July 1957. Nasser had ultimate approval over all the candidates. The constitution granted women's suffrage, prohibited gender-based discrimination, and entailed special protection for women in the workplace. Coinciding with the new constitution and Nasser's presidency, the RCC dissolved itself and its members resigned their military commissions as part of the transition to civilian rule. During the deliberations surrounding the establishment of a new government, Nasser began a process of sidelining his rivals among the original Free Officers, while elevating his closest allies to high-ranking positions in the cabinet.
