The ruling Government Council announced late tonight that presidential elections will be held in November 1987 and that the newly chosen chief of state will be sworn in Feb. 7, 1988.

The nationally televised statement by Council President Lt. Gen. Henri Namphy was an effort to restore calm after a week of demonstrations in which two persons were killed.

It came after a day of closed-door deliberations by Namphy and his Cabinet and put an end to rumors that one or more of the council's three members would resign.

The public clamor for an elections schedule has been growing steadily since the council took power following the fall of president Jean-Claude Duvalier on Feb. 7.

Haitians, more acutely dissatisfied with their nation's extreme poverty since the collapse of the 28-year Duvalier dynasty, looked for an elections agenda as a sign that Namphy is breaking away from his government's apparent paralysis.

The government also announced that elections for members for a constituent assembly will be held in October. A national referendum to approve the new charter is planned for next February.

Namphy said he will not be a candidate for the presidency and that the presidential campaign will officially open in September 1987. Scores of candidates, however, already are on the stump.

Speaking in French, which is only understood by few Haitians, Namphy called for peace and warned, "You must understand it is absolutely impossible for us to carry out the reforms you demand and solve your problems without peace and stability."

Namphy warned, "If you continue to try to clean out all those associated with the old regime, you will only end up cleaning out yourselves."

Namphy delivered a second, much more animated and folksy message in creole, the language spoken by four-fifth of Haitians.

This morning, newspapers here carried a communique signed by 52 politicians and human rights and labor activists calling for the resignation of council member Col. Williams Regala and Finance Minister Leslie Delatour. Regala is linked by some Haitians to Duvalier, while Delatour attracted popular wrath by pressing to close several unprofitable state-run factories.

More than 30 small political groups represented in the communique threatened to call a general strike for Tuesday if their demands are not met.
