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 14 August 2026, at the AK Party's 25th anniversary, 3 MPs (2 from the İYİ Party, 1 independent) joined the AK Party, taking it from 277 to 280. On 24 July 2026 Özgür Özel and 90 other MPs resigned from the CHP and founded 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 334.

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.
