The losing candidate in Indonesia's presidential election, ex-general Prabowo Subianto, will challenge the result in the Constitutional Court, his team's chief lawyer said on Wednesday.
The Elections Commission declared Joko "Jokowi" Widodo the winner on Tuesday in the closely fought July 9 presidential election. The Prabowo team says there was large-scale cheating and accused the commission of not properly investigating the allegations.
"We have decided to bring this case to the Constitutional Court (within three days)," the head of Prabowo's legal team, Mahendradatta, told reporters.
The election was the closest and most bitterly fought election in Indonesia's history, pitting Jokowi against Prabowo, whose promise of strong leadership brought echoes of decades under autocratic rule.
"This victory is a victory for all the people of Indonesia," the president-elect told hundreds of supporters gathered at a port on the outskirts of the capital Jakarta, chosen to emphasize his commitment to Indonesia's maritime potential.
He and his vice president-elect, Jusuf Kalla, arrived by speedboat.
"With humility, we ask the people ... to go back to a united Indonesia," he added.
In an interview with Reuters before the result was announced, Jokowi promised to simplify life for investors by beefing up Indonesia's threadbare infrastructure, unravel near impenetrable regulations and sack ministers if they were not up to the job.
The United States, which sees Indonesia as an increasingly important partner in Asia in the face of growing Chinese power and assertiveness, was quick to offer congratulations.
U.S. Secretary of State John Kerry said bilateral ties had strengthened to the point where the two countries "can jointly address common regional and global challenges."
