The total votes cast in the 1970 election were 34.9 million, out of which 17.1 million were from East Pakistan and 17.7 million were from West Pakistan. 55% and 61% of people cast their votes in the eastern and western halves of the country.

Awami League won 160/162 contested seats and won 75.1% of the votes from East Pak. PPP won 81/120 contested from West Pak, PPP obtained 41.6% Punjab, 44.9% Sindh, 14.2 NWFP%, and only 2.3% of votes in Balochistan. AL obtained 0.7% of votes from West Pak.

PPP fell short of 50% votes, gaining only 2% of votes from Balochistan. Bhutto could, therefore, not justifiably claim to be speaking for West Pakistan.
After the election the initial reaction of Yahya was:
"As far as I am concerned my job is finished."

Three days later at Dacca Yahya met Mujib, in the meeting Mujib explained AL's six points and added that while spelling them out in detail during the NA session, he would tone them down sufficiently to ensure that the idea of the unity of the country remains intact.
