Turkey's main opposition says to formally seek annulment of referendum

Despite a state of emergency and a widespread crackdown on dissent, Erdogan succeeded in persuading only 51.4% of voters to back the constitutional reforms.

Mr Yildirim said the "the path to seek rights" should be limited to legal objections and urged the opposition to accept the vote's outcome. "We can conduct a vote of confidence on this as well".

The opposition is particularly incensed by a last-minute move by the YSK to accept ballot documents in envelopes without an official stamp.

Worldwide observers agreed the campaign was conducted on an "unlevel playing field" and that the vote count itself was marred by procedural changes that removed key safeguards.

In a statement released Monday evening, the White House said that Trump called Erdogan "to congratulate him on his recent referendum victory" and to discuss the United States' military assault on a Syrian military airfield early this month.

Late changes in counting procedures "removed an important safeguard and were contested by the opposition", the report added.

Bulent Tezcan, CHP deputy leader, said the YSK decision sparked a "serious legitimacy crisis", in an interview with CNN-Turk television.

Republican People's Party leader Kemal Kilicdaroglu accused the electoral board of bias and of favoring the governing party. Critics have warned that passing the constitutional changes would be a serious blow to democracy and benefit Erdogan and his purge of political enemies including media that is critical of his rule.

Hundreds of people lined up outside election board offices in Ankara and Istanbul to submit petitions requesting the board reverse its pronouncement.

Nigeria's President Muhammadu Buhari on Tuesday felicitated with the people and government of Turkey on the successful conclusion of the country's referendum on Monday.

Turkey's new political system is due to come into effect after elections in November 2019.

The president's ruling AK party argues that Turkey's current fragile economic and security situation needs strong leadership.

Meanwhile, OSCE monitors were seen entering the Supreme Electoral Board headquarters.

His comments came as the YSK met to evaluate appeals to annul the referendum and after the bar association and an global monitor said the board had acted illegally by allowing unstamped ballot papers to be counted, and may have swung the vote. The placards reads in Turkish: "No we will win".

Protesters were fewer in number in Ankara, where they were outnumbered by police officers.

Mr. Erdogan, speaking from his official residence in Istanbul on Sunday, said the referendum had closed the door on Turkey's long history of military intervention in government.

The European Union opposed Erdogan's bid to shift the country to a system giving the president sweeping new powers.
