National Opposing Union

The National Opposing Union (Unión Nacional Opositora, abbreviated as UNO) was a Salvadoran political coalition which existed from 1972 to 1979. The coalition was composed of the Christian Democratic Party, the National Revolutionary Movement, and the Nationalist Democratic Union.

History
The coalition was formed to oppose the National Conciliation Party, the military controlled political party which controlled El Salvador. UNO ran in the presidential elections of 1972 and 1977. The elections were rigged however and despite sources claiming that UNO won both elections, official reports stated that the PCN won both elections.
