Trump, Erdogan to meet in May: Turkey FM

Turkey's ruling AK Party set out plans on Wednesday for President Tayyip Erdogan to gradually take back the party reins, in a sign it would begin implementing changes approved in Sunday's referendum despite opposition attempts to annul it.

The voters also turned Turkey's parliamentary system into a presidential one.

He also weighed in on the conflict with North Korea, as the country's vice foreign minister threatens weekly missile tests and that there would be "all-out war" if the United States took military action in response.

Turkey's main opposition party has filed a formal request seeking the referendum to be annulled because of voting irregularities.

"We have said this over and over in my speeches".

The opposition has cited several problems with how the vote was conducted.

But the tight result of a highly charged campaign laid bare divisions, while European observers and the head of Turkey's bar associations union said a decision to count unstamped votes broke electoral law.

Global monitors said the move undermined safeguards against fraud.

"What makes any country a democracy is the security of the ballot boxes", Feyzioglu told Reuters. "It is wrong to speak after the people have spoken".

The High Electoral Board said it had assessed appeals from the CHP and two other parties at a seven-hour meeting, and rejected them by 10 to one.

The board's decision to accept ballots without official stamps was like "changing the rules midgame", he said.

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

"Efforts to cast a shadow on the result of the vote by spreading rumours of fraud are futile and in vain", Mr Yildirim said.

Turkey voted on Sunday to switch to a presidential system, greatly increasing Erdogan's powers.

The changes, most of which are due to come into force after November 2019, are some of the most far-reaching in Turkey since Mustafa Kemal Ataturk established the modern state in the ashes of the Ottoman Empire in 1923. The president will also be allowed to keep his ties to a political party.

On Tuesday, Yildirim said Erdogan would be invited to join the party as soon as the official results are declared.

Asked to comment about Erdogan's rebuke, Ms de Zulueta said: "I don't have an opinion, we are invited by the Turkish authorities to observe". We are invited by the Turkish authorities to observe. "We share our report and we completed our mandate".

Protests were reported in at least 20 Turkish cities, including the largest three, namely Istanbul, Ankara and Izmir, in which thousands have been demanding the annulment of the referendum.

Turkey has long called for the U.S. to extradite Islamic preacher Fethullah Gulen, who Ankara has accused of orchestrating the failed July 15 military coup d'état.

US President Donald Trump has become the first Western leader to congratulate Turkish President Recep Tayyip Erdogan for winning a controversial referendum that grants him far-reaching, largely unchecked powers.
