General elections were held in Bolivia on 3 July 1966.
[1] René Barrientos of the Front of the Bolivian Revolution (FRB) was elected president with 67% of the vote,[2] whilst the FRB won a majority in both houses of Congress.
James Dunkerley describes the election as not free and fair since a major segment of the opposition was excluded from participating.
[3] Following the 1964 elections, Barrientos had led a military coup to remove Víctor Paz Estenssoro from power.
In May 1965, Juan Lechín Oquendo, a labor leader who was the head of the left faction of the Nationalist Revolutionary Movement, was arrested and expelled from the country.
