The Broad Front (Spanish: Frente Amplio, FA) was a Chilean political coalition founded in early 2017, composed of left-wing parties and movements.

The Broad Front also expanded their electoral representation to 20 deputies (out of 155), 1 senator (out of 43) and 21 out of 278 Regional Councillors, thus consolidating the movement as the 'third force' in Chilean politics.

[23] The Broad Front's origins lay in the 2011 Chilean student movement, the second biggest social protest in the country's recent history since the restoration of democracy in 1990.

In the 2014 Chilean general election, both Jackson and Boric became MPs after running as independents and defying both traditional coalitions: the center-right Chile Vamos and the center-left Nueva Mayoría (formerly, Concertación).

At early 2016, it was reported that Boric and Jackson held talks with several political and social movements in order to create a "broad left front" of anti-establishment forces, aiming to have a parliamentary list and a presidential candidate for the 2017 general elections.

[24] By August 2016, Boric's Autonomist Movement and Jackson's Democratic Revolution made a formal alliance with the Libertarian Left, New Democracy and the Humanist Party.

[30] As of September 2017 — and according to several opinion polls — Beatriz Sanchez was fighting closely with Nueva Mayoría candidate, Alejandro Guillier, to make it into the second round of and face businessman and former president Sebastián Piñera.

Among the notable figures were (besides those currently serving as MPs at that time) former presidential candidate Tomás Hirsch, journalist Pamela Jiles, student leaders such as former FECh president Camila Rojas and several others.

After the 2017 elections, a reorganization process took place among the members of the coalition: in January 2018, the Autonomist Movement (MA) began organizing convergences or mergers in order to become a new political party,[33] and on November 10, 2018, a meeting between the MA, Libertarian Left (IL), New Democracy (ND) and Socialism and Freedom (SOL) was held at the Huemul Theater, which led to the creation of the Social Convergence party in May 2019.

[42] According to said statement, the following facts were taken into consideration when agreeing to carry out said consultation: the participation of the Democratic Revolution, the Liberal Party and Comunes in the agreement with the government for a new constitution; the resignation of the PEV and the PI; the destructuring of Social Convergence with the departure of the mayor of Valparaíso Jorge Sharp and part of Libertarian Left,[43] in addition to the departure of several grassroots political and social groups such as the MDP.

Castillo, Vidal and the two PL deputies -Vlado Mirosevic and Alejandro Bernales- announced the creation of a new center-left platform on December 16 called “Nuevo Trato” (New Deal).

[47] On December 22, 2020, the Broad Front made official a pact with Chile Digno, formed by the Communist Party, the Social Green Regionalist Federation and Humanist Action.

[55][56][57][58][59][60][61] During the second round, the close circle of his cabinet was formed by the former president of the Medical Association Izkia Siches as head of the campaign, the deputy Giorgio Jackson as political manager and the sociologist Sebastián Kraljevich as strategy leader.

[66] A year later, the leaders of Apruebo Dignidad admitted that the coalition had ceased to function, explaining that the coordination of the pro-government parties was carried out under the organization of the Government Alliance.
