RAWALPINDI, Pakistan, Nov. 26 — In a move evidently aimed at crushing small but potentially dangerous source of opposition to his regime, President Agha Mohammad Yahya Khan today banned the National Awami party.

He said here that the National Awami party — not to be confused with the Awami League, which was banned last March—has “for a long time been acting against the interests and security of Pakistan.” He said he had ordered the detention of some of its leaders.

The President added, however, that party members who had been ‘elected last December to seats in the National Assembly and various provincial assemblies would be permitted to take their places when the assemblies are finally convened early next year.

The National Awami party has two factions, one strongly leftist and inclined toward Peking. This faction's small political base is in East Pakistan, It is led by Maulana Abdul Bhashani This group won no seats in last December's election, and Mr. Bhashani is living in exile in New Delhi.

Other Group a Problem

The other group led by Khan Abdul Wali Khan, poses much more of a problem for the military Government in that it potentially exposes Pakistan's rear area to the type of separatist movement that developed in East Pakistan.

The Wali Khan group, some what pro‐Moscow, is basically a Pathan nationalist group.

Pathans living in Pakistan and neighboring Afghanistan, known for centuries as relentless warriors, have campaigned off and on in recent years for creation of an independent Pathan state to be known as Pushtunistan.

Afghanistan, whose relations with Pakistan have not always been friendly, has periodically promoted the idea, much to Pakistan's chagrin.

Last December” the faction won only 6 seats’ out of 313 in the National Assembly, 12 in the North‐West Frontier provincial assembly of 40 seats, and 8 in Baluchistan's provincial assembly of 20 seats.

But Pathan nationalism can never be safely ignored in Pakistan.

During the last week, several persons have been arrested on charges of spying for India and bringing their information to the autonomous tribal territory along Pakistanis westernmost flank to convey to Indian agents.

Various right‐wing and ultra religions political groups: have demanded in recent months that’ the National Awami party be banned. They argued that the party could pose a wartime danger in West Pakistan. President Yahya's statement today particularly denounced Khan Abdul Ghaffar Khan, a leader of the National Awami party, as the most inveterate of all the opponents of Pakistan.”

‘Gandhi’ of Province

Mr. Ghaffar Khan, described by some Pathan nationalists as “the Gandhi of the North‐West Frontier,” now lives in Afghanistan across the border.

His recent statements have strongly supported the cause of the Bengalis in East Pakistan, but at the same time he has argued for a united Pakistan.

Mr. Ghaffar Khan said his party had split with Sheik Mujibur Rahman's Awami League because the league had sought separate legislatures in East and West Pakistan. Mr. Ghaffar Khan said that would have divided the country.

Meanwhile, the leader of West Pakistan's majority party, Zulfikar Ali Bhutto, conferred today with President Yahya. Mr. Bhutto, said earlier that his party, the leftist Pakistan Peoples party, would, not participate in any future “puppet” government in West Pakistan.

Mr. Bhutto alluded to the current by‐elections in East Pakistan, where, in effect, the Government has appointed right wing politicians to replace the Bengali nationalists elected last December. He said that while the “bitter pill” had to he swallowed in East Pakistan, “there can be no double fraud involving a puppet government in West Pakistan as well.
