Protests Continue For Fourth Night In Wake Of Turkey Referendum

According to unofficial results, the "yes" campaign won with 51.41 percent, while the "no" votes stood at 48.59 percent.

Hundreds of Turkish citizens also lined up outside election board offices in Ankara and Istanbul on Tuesday, to submit petitions requesting the board to reverse its declaration following the referendum results.

Earlier on Wednesday the main opposition Republican People's Party (CHP) threatened to boycott the parliament in protest against what it described as "illegitimacy of the referendum" and called on Turkey's electoral body to nullify the election results and announce a new referendum.

The pro-Kurdish opposition HDP, which had appealed along with the CHP for the referendum to be annulled, said the late decision by the electoral board to allow unstamped ballots meant it was impossible to determine how many invalid or fake votes may have been counted.

On Monday, the White House said in a statement that Trump called Erdogan to congratulate him on his referendum victory and to thank him for supporting a US missile attack on Syria in response to a chemical attack by Syrian government forces on April 4.

On Sunday, Turkey narrowly voted to give President Recep Tayyip Erdogan sweeping new powers and replace their parliamentary system with a presidential one.

"We do not recognise the referendum result", said CHP spokeswoman Selin Sayek Böke.

He says the party's next stop is Turkey's constitutional court and, if it is unsuccessful there, then the European Court of Human Rights.

Some 2,000 protesters in Istanbul Wednesday evening demanded the resignation of the electoral board and chanted "Don't be silent, shout out, "no" to the presidency".

Observers from the Organization for Security and Cooperation in Europe (OSCE) and the Council of Europe said Sunday's referendum had been an uneven contest. Opposition parties have complained of a series of irregularities, particularly an electoral board decision to accept ballots without official stamps, as required by Turkish law. "From the German government's point of view, Turkey must. clear up the questions that have been raised".

"That the Turkish leadership didn't like the criticism by the OSCE's election observer mission isn't a surprise to anyone", German Foreign Ministry spokesman Martin Schaefer said.

Turkish Foreign Minister Mevlet Cavusoglu on Wednesday accused the OSCE of bias and deliberately putting errors into its report.
