Guillermo Ungo, 59, who headed the political wing of El Salvador's guerrilla movement, died of a heart attack today in Mexico City. He returned from exile in Panama in 1989 to head his own party, the National Revolutionary Movement. Mr. Ungo was a candidate for the Salvadoran National Assembly in elections set for March 10 and had been a presidential candidate in 1989. He served on El Salvador's governing junta from 1979 to 1980 and in 1972 ran for vice president on the ticket headed by the late former President Jose Napoleon Duarte. After the junta was dissolved, Mr. Ungo and other members formed the Revolutionary Democratic Front, the political wing of the Farabundo Marti National Liberation Front guerrilla movement.
