Portugal:

The country continued to be governed by a Junta de Salvação Nacional until the Portuguese legislative election of 1976. It was won by the Portuguese Socialist Party (PS) and Mário Soares, its leader, became Prime Minister of the 1st Constitutional Government on 23 July. Mário Soares would be Prime Minister from 1976 to 1978 and again from 1983 to 1985. In this capacity Soares tried to resume the economic growth and development record that had been achieved before the Carnation Revolution, during the last decade of the previous regime. He initiated the process of accession to the European Economic Community (EEC) by starting accession negotiations as early as 1977.
