PORT-AU-PRINCE, HAITI, JAN. 24 -- Officials declared today that university professor Leslie Manigat won last week's presidential election with 50.3 percent of the vote.

Opposition and church leaders repeated claims that the military-led transitional government had rigged the vote to set up a figurehead president behind which the Army could retain real power. The three-man ruling council, led by Lt. Gen. Henri Namphy, has promised to hand power to an elected president on Feb. 7, two years after the fall of dictator Jean-Claude Duvalier.

The government-appointed electoral board said Manigat had received 534,080 votes out of 1,062,016 cast. The council said 35 percent of eligible voters had cast ballots, but opposition groups said authorities had inflated the turnout.

The government scheduled the Jan. 17 balloting after an independently run election Nov. 29 was canceled when gangs of gunmen massacred voters at the polls. Witnesses said soldiers had permitted the attacks and, in some cases, joined in them. The leading candidates in that election refused to take part in the junta-run balloting.

Final results from last week's vote showed sociologist Hubert DeRonceray second with with 210,526 votes, agronomist Gerard Philippe-Auguste third with 151,391 and attorney Gregoire Eugene fourth with 97,556. Mayors and members of the National Assembly also were elected.

{Manigat said he would not be a puppet of the Army, Agence France-Presse reported. "I sincerely believe the Army . . . wants to go back to the barracks," he said. He conceded that some in the military had acquired "some habits" at holding power and that "it is normal that there should be an adjustment period."

{Manigat said he would build a democratic government and persuade western nations to resume aid, which has been cut off in recent months, AFP reported. "During the dictatorship we had a brutal government . . . and despite all that aid was given generously until the end," he said.}
