Pacte Progressista

The Pacte Progressista, officially the Pacte Progressista d'Eivissa, is an electoral alliance formed in Ibiza by the Socialist Party of the Balearic Islands, United Left of Ibiza, The Greens of Ibiza, Entesa Nacionalista i Ecologista and Republican Left of Catalonia to contest the 1999 and 2003 regional elections. Previously, it had contested the 1996 Senate election in the Ibiza–Formentera constituency as Eivissa i Formentera al Senat, and it would also contest the 2000 Senate election as the Pacte per Eivissa i Formentera.
The alliance would be reestablished as "Eivissa i Formentera al Senat" ahead of the 2023 Spanish general election with PSOE, Sumar, EU and Ara Eivissa as its components.

Background

Ahead of the 1996 general election, Ibiza and Formentera only elected one senator to the Spanish Cortes. The disunity of the nationalist and left-of-centre forces always meant that the senator was won by right-of-centre parties. As a result, the Pact was meant as a unitary candidacy of all left parties, obtaining a great electoral success by winning the senator from the People's Party.
