JAKARTA: Indonesia's electoral body formally declared Prabowo Subianto as the country's president-elect in a ceremony on Wednesday, after the Constitutional Court rejected challenges to his landslide victory lodged by his two defeated rivals.

The current defense chief won the election with 58.6 percent of the votes, or more than 96 million ballots, more than twice the amount received by either of the other two candidates. But his rivals alleged that his victory had depended on large-scale fraud and widespread state interference.
