Seat distribution of the Turkish Parliament · 1950 → today
The current seat distribution of Turkey’s Grand National Assembly (TBMM) and how it has changed since 1950. On this page: verified results of 20 general elections, every change between them (party switches, resignations, deaths, loss of seat, party bans, coups) and the sourced current composition — on a single timeline, today at the top, 1950 at the bottom.
The centre line marks the majority threshold (301). Forming a parliamentary group requires 20 MPs.
Parliament today: 592 filled, 8 vacant. On 31 August 2026 Bursa MP Cemalettin Kani Torun resigned from Yeni Yol and became independent, taking the group down to 19. To keep the group alive, Yeniden Refah's Konya MP Ali Yüksel moved to Yeni Yol, restoring it to 20. Earlier, on 14 August 2026, 3 MPs joined the AK Party (277→280), and on 24 July 2026 Özgür Özel and 90 other MPs resigned from the CHP to found the YENİ Party; the CHP fell from 135 to 44, losing main-opposition status after 24 years, while the YENİ Party became parliament's second party with 91 seats. The AK Party alone holds 280 (below the 301 majority); the People's Alliance (AKP+MHP+YRP+HÜDA PAR) holds 333.

Seat distributions: taken from each general election's Wikipedia results table (ultimate source: YSK) and cross-checked exactly against that term's chamber size (487–610 historically; 450, 400, 550, 600). The 1961–1980 figures are based on the National Assembly (lower house, 450).
Between-election events: compiled and cross-verified from the “Nth Parliament of Turkey” (EN) and “TBMM N. dönem milletvekilleri listesi” (TR) pages of the 21st–28th terms; major 1950–1999 events (party bans, splits/mergers, the execution of Menderes, the death of Özal) were also researched. The official TBMM website offers no event dataset (only the current seat distribution and a “members whose term has ended” exit list).
Note. Low-confidence events and those the source does not date are shown faded/grouped; event coverage is expanded over time.
