Following disastrous riots in late 1968 and early 1969, Ayub Khan resigned and handed the government over to Gen. Agha Muhammad Yahya Khan on March 25, 1969 who then declared martial law. Pakistan was now under the grip of another Martial Law.
Unlike other military rulers who ruled Pakistan, Yahya Khan was not interested in prolonging his rule. Being deeply aware of the explosive political situation in the country, General Yahya Khan set in motion moves to transfer power to the elected representatives of the people and announced that the general elections would be held on October 5, 1970.
On March 30, 1970 through an Ordinance, he presented an interim constitution: The Legal Framework Order. The Legal Framework Order was actually a formula according to which the forthcoming elections were to be organised. It goes to the credit of Yahya Khan that the first General Elections in the history of Pakistan were held during his regime. His other important step was to dismiss the concept of West Pakistan as one unit in July, 1970.
