Past elections and referendums
Election results 1975-2019
Autonomous Regions elections
Portugal has two autonomous regions, Azores and Madeira, that elect their own representatives for the regional parliaments every 4 years. The first elections were in 1976 and usually they were both held in the same day until 2007 when Madeira held an early election and Azores held its election the next year. The last election in Azores was in October 2016, and Madeira held an election on September 2019.
Under the Portuguese Constitution adopted in 1976, in the wake of the 1974 Carnation Revolution, the President is elected to a five-year term; there is no limit to the number of terms a president may serve, but a president who serves two consecutive terms may not serve again in the next five years after the second term finishes or in the following five years after his resignation. The official residence of the Portuguese President is the Belém Palace. The President is elected in a two-round system: if no candidate reaches 50% of the votes during the first round, the two candidates with the most votes face each other in a second round held two weeks later., the 1986 presidential election was the only time a Portuguesepresidential election was taken into a second round. The most recent election was held in 2016 and the next is expected to be in 2021.
Referendums
The Constitution of Portugal defines referendum in Article 115. The referendum is called by the President of Portugal, on a proposal submitted by the Assembly or the Government. The President can refuse a proposal for referendum submitted to him by the Assembly or the Government if it is found to be unconstitutional or illegal. Referendums are binding if turnout is higher than 50% of registered voters. Citizens of Portugal have the right to submit to the Assembly an initiative for a referendum. The referendum can be held only on "important issues concerning the national interest which the Assembly of the Republic or the Government must decide by approving an international convention or passing a legislative act". The referendum cannot be held on amendments to the Constitution, budget, taxes, finances and competences of the Assembly, except when issue is the object of an international convention, except when the international convention concerns peace or the rectification of borders. There have been four nationwide referendums in the History of Portugal:
The Constitutional referendum of 1933 did not comply with the standards of a democratic suffrage, as, for example, abstentions were counted as supportive votes. It resulted in the establishing of the Estado Novo regime. The later three referendums, held in the context of a Western-styleliberal democracy had turnout less than 50%, so they were not binding. Nonetheless, decisions of all three referendums were honoured.
