More than 1.6 million votes were disqualified in the July 25 elections—the highest ever. A look at trends shows that it was never this high. In 1993, only 0.27 million votes were disqualified. This number slowly goes up every election year. It levels out in the 2013 general election when roughly 1.5 million votes were disqualified.
