Chile

Presidential succession (1990–present)

Rows highlighted FSP mark presidents from a Foro de São Paulo member/affiliated party.

Legislative composition

Seats by party for recent elections, and whether the governing coalition held a majority. In a fragmented system a governing majority is assembled across several parties — no party governs alone; a coalition majority is not a single-party majority. Each bar orders blocs left→right with a marker at the majority line.

FSP member parties (highlighted FSP): Partido Socialista de Chile (PS), Partido Comunista de Chile (PCCh). Chile's FSP members are the Partido Socialista (PS) and the Partido Comunista (PCCh); the Forum's own roster also lists smaller groups (Izquierda Ciudadana, Partido Humanista, MIR). Crucially, these parties have always governed as a minority faction inside broad center-left coalitions — the Concertación (1990–2010, led by the non-FSP Christian Democrats), the Nueva Mayoría (which added the PCCh from 2013), and Boric's Apruebo Dignidad (2022–, Frente Amplio + PCCh). The PS and PCCh have never commanded a congressional majority on their own: the 2025 seat tables below show them holding just 22 of the Chamber's 155 seats and 10 of the Senate's 50 — a minority even within the Unidad por Chile bloc they share with the (non-FSP) Frente Amplio, PPD, Christian Democrats, Radicals and Liberals. Boric's 2022–2026 government likewise lacked a majority in either chamber.

2025 — Cámara de Diputadas y Diputados (155 seats; majority = 78)

FSP member parties together: 22 of 155 (14%) — 56 seats short of the 78-seat majority. The FSP parties sat in opposition.

Government: José Antonio Kast (Partido Republicano) — lacked a majority. FSP party in government: no. The Chamber was fully renewed on 16 November 2025 for 2026–2030. President-elect Kast's Partido Republicano anchors the Cambio por Chile bloc; with the traditional right (Chile Grande y Unido) the governing right holds 76 of 155 — short of the 78-seat majority, so it relies on the Partido de la Gente (14) and independents. The FSP members PS (11) and PCCh (11) sit in opposition inside the 61-seat Unidad por Chile bloc and are a small minority of the chamber; the non-FSP Frente Amplio (17) is the bloc's largest party.

2025 — Senado (50 seats; majority = 26)

FSP member parties together: 10 of 50 (20%) — 16 seats short of the 26-seat majority. The FSP parties sat in opposition.

Government: José Antonio Kast (Partido Republicano) — lacked a majority. FSP party in government: no. Full post-election composition. The Senate renews by halves — 23 of the 50 seats were up on 16 November 2025, combined here with the 2021 holdovers. The governing right (Chile Grande y Unido 18 + Cambio por Chile 7 = 25) is level with the centre-left and others (Unidad por Chile 20, FRVS 3, 2 independents = 25), so neither side holds the 26-seat majority. The FSP members PS (7) and PCCh (3) sit in opposition within Unidad por Chile. (source 1, source 2, source 3)

High court — Corte Suprema de Chile

Seats

21

Appointment

Justices proposed by the Court itself, chosen by the President, and confirmed by 2/3 of the Senate.

Changes (FSP era)

No court-packing by left governments. Judicial appointments followed the regular mechanism. Two constituent processes (2021–2023) to replace the 1980 constitution both failed at referendum, leaving the judiciary’s structure unchanged.

How much remains

The 21-member court is independent; no FSP-driven structural change — a contrast case. Members are not itemized here.
