More Than 53.7 Million Voters İn Turkey Head For Key Parliamentary Polls

More than 53.7 million Turkish voters head to the polls on June 7 for a crucial parliamentary election.

The ruling Justice and Development Party (AKP) has framed the June 7 election in Turkey as a key hurdle on the path to the powerful presidential system that President Recep Tayyip Erdoğan wants to introduce.

However, if the Kurdish problem-focused Peoples' Democratic Party (HDP) crosses the 10 percent election threshold, the number of AKP lawmakers will decrease considerably, making it almost impossible to reach the 330 seats necessary for a constitutional change.

The HDP has faced scores of physical attacks during its campaign. One of its campaign bus drivers, Hamdullah Öğe, was murdered on June 3, and two of its supporters were killed when twin bomb blasts hit its milestone rally in the southeastern province of Diyarbakır on June 5.

Election safety has also been a hot item on the agenda during the campaign ahead of the vote, amid the opposition's claims that there was fraud in the vote counting process. The government has strictly denied the claim and mobilized a total of 404,000 security personnel to maintain security throughout the day of the election.
