Turkey opposition says irregularities at thousands of ballot boxes

Erdogan's ruling Islamist-rooted AK Party and its nationalist allies surprised pollsters by winning a strong majority in parliament.

In the presidential vote, Erdogan is headed for a runoff on May 28 against challenger Kemal Kilicdaroglu after falling just shy of the 50 percent threshold needed to win outright in the first round.

Kilicdaroglu, the CHP chair, received 44.9 percent in what was seen as the biggest electoral challenge to Erdogan's 20-year rule. A third candidate, Sinan Ogan obtained 5.17 percent.

"We are following every single vote, even if it does not change the overall results," Erkek told reporters in Ankara.

There were a total of 201,807 ballot boxes set up for the election, in Turkey and abroad, Erkek said.

The deadline for challenging the results of the presidential election expired on Monday, while that for the parliamentary vote expired on Tuesday, Erkek said, adding that the CHP had filed all its appeals within these timeframes.

The opposition alliance that includes the CHP has appealed to young voters, in particular, to turn out to support Kilicdaroglu in the runoff, saying the first round showed that Erdogan had lost the vote of confidence he had sought.

Erdogan, now in pole position, says only he can ensure stability in Turkey, a NATO member state, as it grapples with a cost-of-living crisis, soaring inflation and the impact of devastating earthquakes in February.
