Honduras ? A wealthy landowner who promised to battle corruption was declared Honduras’ president-elect Monday by an election official from his party, but the results were immediately contested by his opponent and a rival election official.

Supreme Electoral Tribunal President Aristides Mejia, of the Liberal Party, declared Manuel Zelaya the winner, but tribunal members said preliminary official results would not be available until today at the earliest.

Zelaya’s opponent, Porfirio Lobo Sosa of the ruling National Party, refused to concede, saying the votes had not yet been counted in full. On Monday night Jacobo Hernandez, an electoral tribunal representative and also a member of the National Party, echoed his complaint.

The tribunal said Sunday night that Zelaya had 50.8 percent of the vote to 45.2 percent for Lobo Sosa of the governing National Party, but added that the numbers were based on a small number of votes.
