“We are going to evaluate the objections before noon,” Sadi Guven told reporters in Ankara Wednesday morning.

On Sunday, a majority of Turkish voters cast their ballots in favor of 18 constitutional amendments that will, among other things, see Turkey switch from a parliamentary to a presidential system of governance.

According to unofficial results, the Yes campaign won with 51.41 percent, while the No votes stood at 48.59 percent. Voter turnout was 85.46 percent.

However, the main opposition Republican People’s Party (CHP) challenged the result.

On Tuesday, CHP leader Kemal Kilicdaroglu slammed the Supreme Election Board's decision to count unsealed ballots in the referendum.

Kilicdaroglu said he respected the nation's will but the decision on unsealed ballots had overshadowed the results.

"The rule of a match cannot be changed while the match is being played, this is a universal rule," he said.
