ANKARA — Expected changes to the Turkish constitution will be fully implemented with the presidential elections scheduled for November 2019, President Tayyip Erdogan said on Tuesday, in an apparent response to a suggestion for early polls. Erdogan's comments came after the head of the nationalist MHP party suggested holding presidential elections in August this year. Turks narrowly backed a constitutional change last year to change the constitution and grant Erdogan sweeping powers. The changes are due to become effective in the next elections. Turkish deputy prime minister said the ruling AK Party would discuss a suggestion by the nationalist MHP party to hold the presidential election in August this year, more than a year before the November 2019 scheduled date. MHP leader Devlet Bahceli suggested on Tuesday bringing forward the presidential election, saying it was difficult for the country to stand current circumstances until November 2019. The party's official institutions will make an evaluation and a statement will be made afterwards, Deputy Prime Minister Bekir Bozdag told reporters. President Tayyip Erdogan said he would meet Bahceli on Wednesday. Turkey's lira weakened to 4.1103 by 0941 GMT, from 4.0865 before Bahceli's comments. The Borsa Istanbul main stock exchange index fell more than 2 percent. The leader of Turkey's main nationalist party, who has become a key ally of President Recep Tayyip Erdogan, on Tuesday urged the holding of snap elections this August in comments that stunned Turkish politics. Devlet Bahceli, who heads the Nationalist Movement Party (MHP), said that Turkey could not wait for November 3, 2019, when presidential and parliamentary elections are due to be held simultaneously. He told a meeting of his party in Ankara that instead the elections should be held on August 26, 2018. In this situation it is not possible to wait until November 3, 2019, said Bahceli. On August 26, 2018 the Turkish nation should go to the ballot box in the spirit of marking a new victory, he added. The elections will be a key moment in Turkish history as it is after those polls that the new executive presidency giving the head of state more powers agreed in an April 2017 referendum should come into force. — Agencies
