Today, following his meeting with Bahceli, President Erdogan said the snap parliamentary elections will be held in Turkey on June 24, 2018.
"As result of consultations with Mr Bahceli, we made a decision to hold elections on June 24, 2018, a Sunday", said Erdogan.
Presidential powers have been substantially strengthened through constitutional amendments following a referendum in April of a year ago.
Erdoğan said the country urgently needed to make the switch to an executive presidency.
Turkey is switching from a parliamentary system to a presidential one that increases the powers of the president, following a narrowly approved referendum a year ago.
The elections are especially significant as afterwards a new executive presidency - agreed in a 2017 referendum and denounced by critics as giving the president authoritarian powers - will come into force.
The snap elections were called a day after Bahceli made a surprise call for elections in the summer.
Turkish President Recep Tayyip Erdogan has announced that presidential and parliamentary elections slated for November next year would be held in late June.
Erdogan's Justice and Development Party (AKP) has established a formal alliance with the MHP to fight the elections, in the hope of sweeping up conservative votes.More news: NASA spacecraft aims to put mystery planets on galactic map

Guven said the YSK would investigate in the coming days eligibility conditions to determine which parties can take part in the elections.
"It is likely that an early election is called because of the deteriorating economy and I think that's the most alarming indicator, that's the most important variable right now in deciding the early elections", said Mr Selcuki.
Three weeks after the attempted putsch, Bahceli attended a rally in support of the elected government in Istanbul with other key political leaders at the request of Turkey's President Recep Tayyip Erdogan.
Erdogan needs a 51 percent majority to be re-elected in the first round of the presidential election.
"The government has welcomed [Nationalist Movement Party leader Devlet] Bahceli's idea to hold early elections".
Cagaptay said Erdogan had been "preparing the groundwork to stack the elections in his favour".
Parliament was widely expected to extend the state of emergency for a seventh time despite calls at home and overseas for it to end.
The AKP would like to keep the state of emergency in place throughout the election cycle, though the detrimental effect it has had on the economy means the party would not want to sustain it beyond the vote.
