Tenerife (Parliament of the Canary Islands constituency)

Tenerife is one of the seven constituencies (circunscripciones) represented in the Parliament of the Canary Islands, the regional legislature of the Autonomous Community of the Canary Islands. The constituency currently elects 15 deputies. Its boundaries correspond to those of the island of Tenerife. The electoral system uses the D'Hondt method and a closed-list proportional representation, with a minimum threshold of fifteen percent in the constituency or four percent regionally.

Electoral system
The constituency was created as per the Statute of Autonomy of the Canary Islands of 1982 and was first contested in the 1983 regional election. The Statute provides for the seven main islands in the Canarian archipelago—El Hierro, Fuerteventura, Gran Canaria, La Gomera, La Palma, Lanzarote and Tenerife—to be established as multi-member districts in the Parliament of the Canary Islands. Each constituency is allocated a fixed number of seats: 3 for El Hierro, 8 for Fuerteventura—7 until 2018—15 for Gran Canaria, 4 for La Gomera, 8 for La Palma, 8 for Lanzarote and 15 for Tenerife.

Voting is on the basis of universal suffrage, which comprises all nationals over eighteen, registered in the Canary Islands and in full enjoyment of their political rights. Amendments to the electoral law in 2011 required for Canarian citizens abroad to apply for voting before being permitted to vote, a system known as "begged" or expat vote (Voto rogado) which was abolished in 2022. Seats are elected using the D'Hondt method and a closed list proportional representation, with an electoral threshold of 15 percent of valid votes—which includes blank ballots; until a 1997 reform, the threshold was set at 20 percent; between 1997 and 2018, it was set at 30 percent—being applied in each constituency. Alternatively, parties can also enter the seat distribution as long as they reach four percent regionally—three percent until 1997, six percent between 1997 and 2018.

The electoral law allows for parties and federations registered in the interior ministry, coalitions and groupings of electors to present lists of candidates. Parties and federations intending to form a coalition ahead of an election are required to inform the relevant Electoral Commission within ten days of the election call—fifteen before 1985—whereas groupings of electors need to secure the signature of at least one percent of the electorate in the constituencies for which they seek election—one-thousandth of the electorate, with a compulsory minimum of 500 signatures, until 1985—disallowing electors from signing for more than one list of candidates.
