The Left-wing Revolutionary Nationalist Movement (Spanish: Movimiento Nacionalista Revolucionario de Izquierda, MNRI) was a centre-left political party in Bolivia.
[1] The MNRI sought the establishment of a government "truly representative of workers and peasants"; an end to "fratricidal struggles"; the suppression of the drug trade, and the renegotiation of foreign debt.
In the presidential elections of 1978 Hernán Siles Zuazo, as the UDP candidate, came second with 25.00%, and of 1979 and 1980 he came first with 35.97 and 38.74 per cent, and only the 1980 military coup prevented his inauguration as president.
[3] The Democratic and Popular Union coalition government was increasingly dominated by the MNRI, with the Revolutionary Left Movement withdrawing its support from January 1983 to April 1984, and again from December 1984; the Communist Party of Bolivia withdrew its backing in November 1984.
At least three factions were identifiable: the “Palaciego”, which surrounded Hernán Siles Zuazo; the MNRI-Legalista, which in 1983 joined the opposition in National Congress; and the Leftwing Revolutionary Nationalist Movement – 20th Century, a group of technocrats.
