Opposition to challenge votes on expanding Erdogan's powers

Opposition supporters took to the streets of Istanbul to bang pots and pans, a traditional form of protest, in a series of noisy demonstrations.

Turkey's main opposition party will formally present the Supreme Election Board (YSK) with a demand to annul the result of the referendum, after alleging major violations.

The country's pro-Kurdish party said it may take the case to the European Court of Human Rights if the electoral board does not reverse his decision and nullify the ballots lacking the official stamps.

"Trump called Erdogan tonight and congratulated him on his success in the referendum", government sources said, according to state-run news agency Anadolu.

Unlike the Nigerian leader, the European Union on Tuesday called on Turkish authorities to launch "transparent investigations" after global observers criticised the fairness of the voting process during the recent referendum.

Monitors from the Organisation for Security and Cooperation in Europe, who also listed numerous problems, said the move undermined important election safeguards.

The referendum - which came six months after a military coup failed to unseat President Erdogan - narrowly passed over the weekend, with 51% of voters supporting the vote.

Global monitors have said the vote took place on an "unlevel playing field and the two sides of the campaign did not have equal opportunities".

Speaking to a rally of supporters in Ankara on Monday he said that some European countries had opposed him winning the referendum more than members of the Turkish opposition. The referendum campaign was marred by allegations that Erdogan abused his office to harass political opponents and loosen ballot validity rules to allow last-minute votes. "The legal framework was inadequate for the holding of a genuinely democratic process", said Cezar Florin Preda, head of the delegation from the Parliamentary Assembly of the Council of Europe.

In a statement, the foreign ministry said that the observer mission's findings that Sunday's referendum procedures "fell short" of global standards "were unacceptable".

"I am a mortal really, I could die at any time", he told Becky Anderson inside Ankara's presidential palace Tuesday, in his first interview since the vote.

"We can›t just go back to the daily routine after the Turkey referendum". Under the new system, the president will be able to appoint ministers and senior government officials, issue decrees and declare states of emergency.
