The Azhari government temporarily halted progress toward self-determination for Sudan, hoping to promote unity with Egypt. Although his pro-Egyptian NUP had won a majority in the 1953 parliamentary elections, Azhari realized that popular opinion had shifted against union with Egypt. As a result, Azhari, who had been the major spokesman for the "unity of the Nile Valley," reversed the NUP's stand and supported Sudanese independence. On December 19, 1955, the Sudanese parliament, under Azhari's leadership, unanimously adopted a declaration of independence; on January 1, 1956, Sudan became an independent republic. Azhari called for the withdrawal of foreign troops and requested the condominium powers to sponsor a plebiscite in advance of the scheduled date.
