"We have not made any kind of preparations for snap election... There is no such thing on our agenda," Ahmet Sorgun told journalists in central Konya province.

In response to a question about whether the ruling party intends to hold snap election if Turkish people vote in favor of changing the constitution on Sunday, he said: "Holding elections on time is one of the basic principles of the AK Party."

Sunday’s referendum proposes a host of constitutional reforms that would hand wide-ranging executive powers to Turkey’s president.

The post of prime minister would be abolished and the president would also be allowed to retain ties to a political party.

Other changes include the minimum age of parliamentary candidates getting reduced to 18 and the number of deputies increased to 600.
