Cuba is a republic under the concept of government of "popular democracy" and a socialist state established at various stages after the triumph of the Cuban revolution in 1959. It is a one-party republic which has, since 1980, a parliament and direct and secret election of deputies to municipal, provincial and national parliament. The President of the Council of State is ex officio Head of State, President of the Council of Ministers, Commander-in-Chief of the Revolutionary Armed Forces and the leader of the country. These positions have been occupied since 2018 by Miguel Díaz-Canel. For example, the opening of an internet line is subject to the authorization of the authorities of the island. Internet use must not "compromise state security" or go against "the laws and moral principles of the country", grounds sufficiently vague to arbitrarily cut off access to the Internet.
