Thailand's first election since the 2014 coup was always going to be messy. But it's turning out to be even more chaotic than many observers expected, setting the stage for renewed tumult after five years of military rule.

Election authorities have faced calls to resign for repeatedly delaying the full results and failing to account for mounting irregularities, including one candidate whose vote totals dropped 80 percent at one point during the count. After the Election Commission finally released some seat totals, it issued a correction about an hour later. It plans to release the vote count on Friday.

Based on the limited information available, allies of exiled tycoon Thaksin Shinawatra were set to win the most seats, followed by the military-backed Palang Pracharath party. Now both of them are racing to win over allies to form a majority in the 500-member lower house of parliament.
