JAKARTA: Indonesia’s president on Friday urged the election chief to ensure a transparent vote count following this week’s disputed presidential poll, after both sides raised fears the other may tamper with the ballots.

Political tensions are rising after the tight election in the world’s third-biggest democracy ended with both Jakarta Gov. Joko Widodo and his rival, ex-general Prabowo Subianto, declaring victory on Wednesday. Most credible pollsters gave Widodo a lead in unofficial tallies, but Prabowo said that other polling institutes followed by his team showed he was the winner.

Vote tallying is a long, complex process in the world’s biggest archipelago nation, and results are not expected until July 22.

On Thursday Widodo, known by his nickname Jokowi, expressed fears that the vote count could be manipulated in one of the world’s most-graft ridden countries.
