Current composition -- By province
The Chamber of Deputies (Spanish: Cámara de Diputados de la Nación) is the lower house of the Argentine National Congress (Spanish: Congreso de la Nación). It is made up of 257 national deputies who are elected in multi-member constituencies corresponding with the territories of the 23 provinces of Argentina (plus the Federal Capital) by party list proportional representation. Elections to the Chamber are held every two years; half of its members are renewed each election. The Constitution of Argentina lays out certain attributions that are unique to the Chamber of Deputies. The Chamber holds exclusive rights to levy taxes; to draft troops; and to accuse the President, cabinet ministers, and members of the Supreme Court before the Senate. Additionally, the Chamber of Deputies receives for consideration bills presented by popular initiative. The Chamber of Deputies is presided over by the President of the Chamber (Spanish: Presidente de la Cámara), who is deputized by three Vice Presidents.
