RAWALPINDI, Pakistan, June 28—President Agha Mohammad Yahya Khan of Pakistan told his people today that they could expect to have a popularly elected legislature in about four months.

In a speech to the nation, President Yahya Khan said that he considered the results of the elections held last Dec. 7 for a National Assembly and for local provincial assemblies still valid.

But the President said that although Pakistan would move toward democracy as rapidly as possible, martial law would remain in effect for some time to keep the country from chaos.

General Yahya Khan said that national and provincial governments would be formed when the assemblies were convened, but he did not say what farm such governments would take.

A Watchdog Role

The speech indicated that any new Government would he subject to certain guidelines, with the armed forces maintaining a watchdog role.

General Yahya Khan said that there had been indications that major aid‐giving nations were seeking to press Pakistan into a quick political settlement of her problems. He said that Pakistan wholly rejected such pressure and would do without foreign aid if necessary.

Pakistan's economy is largely dependent on foreign aid, of which the United States furnishes about half.

Pakistan, which, with India, became independent of Britain in 1947, has never had a popularly elected government. During most of her history she has been under military rule.

The election of last December was the first of its kind in the nation's history and the results reflected the deep split between the Punjabis and other dominant groups of West Pakistan and the Bengalis of the more populous East Pakistan. East and West Pakistan are separated by about 1,000 miles of Indian territory.

Nearly all the seats allocated to East Pakistan were won by the Awami League, which thus became the majority party of all Pakistan. The runner‐up was the Pakistan People's party, which won all its seats in West Pakistan.

Negotiations on procedure between these two parties and the military Government resulted in a stalemate and last March 1 President Yahya announced that the convening of the National Assembly would be postponed.

The Awami League was pressing for a wide measure of autonomy for East Pakistan and some of its leaders and members advocated outright se cession to form a new Bengali state to be known as Bangla Desh (Bengal Nation). On March 25, armed forces from West Pakistan poured into the eastern wing to suppress the secessionist movement and to clamp military administration on the province. Many thousands were killed, the economy of East Pakistan came to a stand still and millions of Bengal refugees swarmed across the border into India.

The Awami League was permanently banned and its leader, Sheik Mujibur Rahman, was jailed.

In his speech today, the President said that the ban on the Awami League was not in tended to exclude members‐elect of that party from the new National Assembly.

A list of ineligible Awami League members who had committed “antistate” or “criminal” acts was being drawn up, he said, but the others were asked to come forward to serve in the legislature as individuals.

New Constitution Planned

A special commission has been appointed, the President said, to prepare a new constitution to go into effect at the first sitting of the National Assembly. A draft of the constitution will be shown to various political leaders for comment and possible revision. But the President said that he would ban splinter parties and those with a purely regional attraction.

“Since the nation has recently been subjected to a very severe jolt,” he said, “I have decided that the national and provincial governments will have at their disposal the cover of martial law for a period of time. In actual practice, martial law will not be operative in its present form, but we cannot allow chaos in any part of the country and the hands of the governments need to be strengthened until things settle down.”
