Turkey will hold snap parliamentary and presidential elections on June 24th, heralding the switch to a powerful new executive Presidency that was narrowly approved in a referendum last year and championed by President Tayyip Erdogan.

Polls indicate elections may be closer than anticipated when Erdogan called the snap elections in April, suggesting he may be pushed to a second-round run-off for the presidency, and his AKP could lose its majority in the 600-seat assembly.

Support for Erdogan was dipped 1.6 points in one week, according to a survey by pollster Gezici published last week. Other polls have shown that a second round run-off between Erdogan and Republican People’s Party candidate Muharrem Ince could also challenge the President.

With growing concerns over the purges, in addition to a plummeting currency, polls have shown that support for Erdogan may be eroding, suggesting his ruling AK party could lose its majority in the 600-seat assembly.

Meanwhile, critics have accused Erdogan of using a failed coup in 2016 as a pretext to muzzle dissent, pointing to a widespread crackdown in which 160,000 people have been detained and nearly the same number dismissed from their jobs, according to the United Nations.
