Seven candidates are competing in this race, including three from parties in the Grand National Assembly and four "independent candidates".
Muharrem Ince, a staunch nationalist who has been a lawmaker since 2002, was chosen by the centre-left Republican People’s party (CHP) on Friday.
Ince, a 54-year-old former physics teacher from the northwest who is known for his fiery and impassioned rhetoric, is going to challenge incumbent President, Recep Tayyip Erdogan, in this June's presidential elections.
The pro-Kurdish Peoples’ Democratic Party (HDP), which is also strongly critical of Erdogan, has already presented charismatic former leader Selahattin Demirtas as its presidential candidate despite the fact that he is currently jailed, and is on trial in connection with several cases.
The winner of the June 24 vote will govern with broad new powers granted by a set of constitutional amendments fought for by Mr Erdogan in a contentious referendum last year.
Most polls show Mr Erdogan, president since 2014 and before that prime minister for more than a decade, with above 40 per cent support in an increasingly crowded field of candidates.
The first round of voting will be held on June 24. If no candidate has obtained more than 50 percent of the vote, the second round of voting will be held on 8th July. Turkey's Supreme Election Commission will announce the final result on July 12.
