The LV legislative period of the National Congress of Chile was the legislative term that followed the 2017 Chilean parliamentary election. It comprised members of the Senate and the Chamber of Deputies, and ran from 11 March 2018 to 10 March 2022.
In the 2017 electoral process, the Chamber of Deputies was fully renewed; deputies serve four-year terms and therefore served only during this legislative period. Twenty-three senators were also elected, representing the constituencies of Tarapacá, Arica and Parinacota, Atacama, ValparaÃÂso, Maule, AraucanÃÂa, and Aysén. Their eight-year terms extended into the subsequent legislative period.
In the 2013 elections, 20 senators were elected, representing the constituencies of Antofagasta, Coquimbo, Metropolitana, O'Higgins, BiobÃÂo, Los Lagos, Los RÃÂos, and Magallanes; their terms concluded during this legislative period.
This was the only legislative period to operate with a composition of 155 deputies and 43 senators, as established by the electoral reform approved in 2015. From the subsequent legislative period, the National Congress would consist of 155 deputies and 50 senators, completing the composition set out in the reform.
The Senate of the Republic was composed of 20 senators elected in 2013 who were already serving from the previous legislative period, and 23 new senators corresponding to the regions of Tarapacá, Arica y Parinacota, Atacama, ValparaÃÂso, Maule, AraucanÃÂa, and Aysén, elected for an eight-year term, giving a total of 43 senators.
The composition of the Senate in the LV legislative period was as follows:
By decision of the Nueva MayorÃÂa coalition, Socialist senator Carlos Montes Cisternas assumed office as President of the Senate on 11 March 2018.
The composition of the Chamber of Deputies in the 55th legislative period was as follows:
By agreement between the Nueva MayorÃÂa coalition, the Broad Front and the Regionalist Green Social Federation, Socialist deputy Maya Fernández assumed office as President of the Chamber of Deputies on 11 March 2018. The same parties agreed that in the following two years the post would correspond to Christian Democratic deputies, and in the final two years of the government to a Socialist.
