A constitutional referendum was held in Spain on Wednesday, 6 December 1978, to gauge support for either the ratification or repealing of the Spanish Constitution which had been approved by the Cortes Generales on 31 October 1978. The question asked was "Do you approve of the Constitution Bill?" (Spanish: ¿Aprueba el Proyecto de Constitución?). The referendum resulted in 92% of valid votes in support of the bill on a turnout of 67%.[1][2][3]
