Delhi, May 7
Resisting the popular and emotional urges that have built up in India over the trouble in East Pakistan, Mrs. Gandhi, the Prime Minister, today refused to meet the almost unanimous demands of Opposition leaders and recognize the "provisional government of Bangla Desh " without delay.

Mrs. Gandhi, who had three hours of confidential talks with the heads of the main Opposition groups, said the question of extending the Government's recognition to the provisional government was still under consideration.

Replying angrily to taunts that the Government had refused recognition because it feared an attack by China and Pakistan, she reminded political leaders that no other country had recognized the Bangla Desh movement.

"There are many implications and we are fully in touch with all friendly countries", Mrs. Gandhi said.

Almost without exception, leaders of all other political parties wanted Mrs. Gandhi to extend moral and material support to the Liberation Front. Mr. Indrajit Gupta, the pro-Soviet communist leader, went farther and asked Mrs. Gandhi to recognize Bangla Desh immediately and to supply military equipment and food to the Liberation Front.

Mr. A. B. Vajpayee, the spokesman of the Hindu nationalist Jan Sangh party, advocated a militant approach.

In an ominous reference to the non-Bengali minority, who have been hunted and hounded by Pakistan and Indian Bengalis alike, Mr. Vajpayee asked the Government to take every step to see the non-Bengalis did not enter India in the garb of refugees.

Mrs. Gandhi said the Government had decided to introduce preventive detention to deal with "spies" from East Bengal. It is obvious that the Government could use legislation to imprison non-Bengali refugees who cross the Indo-Pakistan border.

This would mean that the non-Bengalis, who are identified linguistically and ethnically with the West Pakistanis would have no means of escaping the vengeance of Bengal nationalism and the reprisals that have sent them across the Indian border during the past few weeks of violence and slaughter.
