Turkish President Recep Tayyip Erdogan had asked Prime Minister Ahmet Davutoglu to form a new government on Thursday.
Releasing a written statement on Friday, CHP leader Kemal Kilicdaroglu said he will meet Davutoglu at the party headquarters on July 13 at 2 p.m. local time (1100GMT).
The Nationalist Movement Party (MHP) leader Devlet Bahceli will meet Davutoglu at his party headquarters on July 14 at 2 p.m. local time (1100GMT).
Davutoglu will meet the Peoples` Democratic Party (HDP) co-chair Selahattin Demirtas and co-chairwoman Figen Yuksekdag at the party headquarters on July 15 at 11 a.m. local time (0800GMT).
Davutoglu said, on Thursday, the first round of the negotiations for a "government partnership" will run to July 15.
"The second round of meetings will be held in accordance with the atmosphere following Eid al-Fitr,"Davutoglu added, referring to post-Ramadan celebrations.
Davutoglu now has 45 days to form a government around the Justice and Development (AK) Party, which gained the largest share of parliamentary seats in the June 7 general election.
Although the party came in first, it did not win enough seats to form a majority government, so it must attempt to forge a coaliton with the three other parliamentary parties - the second-placed CHP, MHP and HDP. Either the left-leaning CHP or the right-wing MHP are likely to be Davutoglu`s preferred partners.
If he is unable to form a coalition, tradition dictates the president should offer the second-place party the chance to create an administration within the same 45-day period. If this does not succeed, the president must call a fresh election and appoint a prime minister within five days to form an interim government consisting of representatives from all four parties.
The new election would likely be held towards the end of November.
