Turkish President Recep Tayyip Erdogan has suffered a serious setback in the parliamentary elections Sunday, according to initial reports. Four hours after the ballots closed, it appeared that Erdogan’s AKP party will not have the required majority for passing reforms in the Turkish constitution.

With 90% of the votes counted, the Kurdish HDP party received about 11% of the votes, according to Turkish-language CNN.

This places it past the 10% threshold required for entering parliament and would give it about 80 MPs. The party has never before passed the threshold.

According to reports, AKP received 42 or 43% of the votes, leaving it short of an overall majority for the first time since its creation more than a decade ago. AKP may be forced to establish a coalition in order to rule Turkey.

“We expect a minority government and an early election,” a senior AKP official told Reuters on condition of anonymity.

Erdogan wanted to change the constitution to grant him greater powers than he currently wields. If HDP enters parliament, this will apparently be impossible.
