Parliamentary elections were held in Turkey on 14 May 2023, alongside presidential elections, to elect all 600 members of the Grand National Assembly. The incoming members formed the 28th Parliament of Turkey. The elections had originally been scheduled to take place on June 18, but the government moved them forward by a month to avoid coinciding with the university exams, the Hajj pilgrimage and the start of the summer holidays. Prior to the election, the electoral threshold for a party to enter parliament was lowered from 10% to 7% by the ruling party.
The elections were contested by a total of 24 political parties. Some parties decided to participate in the elections as part of an electoral alliance, many of which were formed for the previous 2018 election and had been expanded since. The governing Justice and Development Party (AKP) of incumbent President Recep Tayyip Erdoğan lead the People's Alliance, which also included the Nationalist Movement Party (MHP), the Great Union Party (BBP) and the New Welfare Party (YRP). The largest opposition alliance was headed by the main opposition Republican People's Party (CHP) and included five other parties. These included the Good Party (İYİ), the Felicity Party (SP), the Democrat Party (DP) and two other parties headed by former senior AKP politicians, namely the Democracy and Progress Party (DEVA) of former economy minister Ali Babacan and the Future Party (GP) of former Prime Minister Ahmet Davutoğlu. The pro-Kurdish Peoples' Democratic Party (HDP) opted to run on the lists of the Party of Greens and the Left Future (YSGP) in light of a potential closure case. The YSGP itself headed the left-wing Labour and Freedom Alliance along with the Workers' Party of Turkey (TİP). Two smaller alliances, the Ancestral Alliance of presidential candidate Sinan Oğan and the Union of Socialist Forces, also participated in the elections for the first time.
