The opposition faction became known as the Council Muslim League. This latter group joined a united front with other political parties in 1967 in opposition to the regime. But when the military regime of Agha Mohammad Yahya Khan fell in December 1971, and Pakistan's first genuine free elections were held, both factions of the League were swept out of power: in West Pakistan by the Pakistan Peoples Party of Zulfikar Ali Bhutto and in East Pakistan by the Awami League of Sheikh Mujibur Rahman.
