Senate of Spain article 115 of the Spanish Constitution.

Most members of the senate (currently 208 of 266) are directly elected by the people. Each province elects four senators without regard to population. Insular provinces are treated specially. The larger islands of the Balearics (Baleares) and Canaries (Canarias)—Mallorca, Gran Canaria, and Tenerife—are assigned three seats each, and the smaller islands—Menorca, Ibiza–Formentera, Fuerteventura, Gomera, Hierro, Lanzarote and La Palma—one each; Ceuta
Lanzarote include Chinese people, Ecuadorians, and Indians, which constitute a large proportion of the remaining 15.6% of the population. The island has an international airport, Arrecife Airport, through which 5,438,178 passengers travelled in 2008. Tourism has been the mainstay of the island's economy for over 40 years, the only other industry being agriculture. Lanzarote is part of the province of Las Palmas, and is divided into seven municipalities: There are five hundred different kinds of plants on the island, of which 17 species are endemic. These plants have adapted to the relative scarcity of water in the same way as succulents.
