with the nap leadership largely imprisoned, a new political party was formed on the wreckage of the nap in 1976 by sherbaz khan mazari. named national democratic party (ndp), it was headed by sherbaz khan mazari. the hyderabad case was withdrawn after general muhammad zia-ul-haq imposed martial law in july 1977. wali khan left party affairs to sher baz mazari after his release from jail in 1979. the party faced a split at that time between far left elements led by khair bakhsh marri advocating outright separation and armed struggle and those advocating political struggle led by sherbaz khan mazari. the split ended the alliance between pashtun nationalists and baloch nationalists that wali khan had formed in 1969 and led to the formation of the pakistan national party.
