DACCA, Pakistan, March 4— Sheik Mujibur Rahman, the East Pakistani nationalist leader, announced today that he had authorized some relaxation of the general strike he had called to protest the postponement of a constitutional assembly.

With food supplies becoming increasingly short and workers and shopkeepers suffering from the shutdown, now in its third day, Sheik Mujib said he would authorize banks to open for business tomorrow afternoon and factories to start operating at night.

He also ordered a partial restoration of telegraph services today.

With Sheik Mujib and his Awami League moving increasingly away from any recognition of the central Government in West Pakistan, the eastern province with its 70 million people has become a territory that has two centers of power. East and West Pakistan are 1,000 miles apart, separated by Indian territory.

One power is the Awami League, which dominates the National Assembly, having won 167 of its 313 seats with a campaign demanding regional autonomy for East Pakistan. The other consists of the martial‐law authorities, ordered by the military Government of President Agha Mohammad Yahya Khan to take over the civilian administration of the province.

The President issued the order on Monday when he announced that he was postponing the Assembly that was to have met here yesterday to begin drafting a constitution providing for a return to civilian rule. The announced reason for the postponement was a deadlock between West Pakistani and East Pakistani political leaders on the principal provisions of the charter. The West Pakistanis oppose the aims of the Awami League.

Last night the President called a meeting of Assembly leaders for next Wednesday to attempt to resolve the differences, but Sheik Mujib said he would not attend.

The military forces have kept some order during the general strike and enforced a dawn‐to‐dusk curfew. But greater authority rested with Sheik Mujib and the Awami league. Policing was largely done by pole‐wielding activists of the league. The people looked to Sheik Mujib for direction.

Sheik Mujib said he had established control over the central radio station for East Pakistan, which up to today had been administered by authorities in the west, and which had been giving only meager coverage to the East Pakistan nationalist movement.

The leader reiterated to newsmen today his determination to continue his nationalist course. He said that on Sunday, the day he has set for a major policy statement, he would announce a constitution, implying this would be a step that would virtually establish self‐rule for East Pakistan.

“We shall have our constitution,” he said, “and they in the west can have theirs. Then we can see how we can arrange to cooperate.”
