[14][15][16] While campaigning for the 2015 Spanish general election, the United Left (IU) promoted the creation of, and later joined, the Now in Common (Ahora en Común, AeC) platform, seeking a wide alliance with other left-wing parties.

[17] After Podemos rejected invitations to join to what some members of this party called an "acronym soup", heightened after the failure of Catalunya Sí que es Pot in the 2015 Catalan election,[18] the AeC platform gradually lost momentum: its founding members left the project and the brand name was lost.

[19] From 20 April 2016, Podemos and Popular Unity were reported to be in negotiations to form a joint electoral list for upcoming general election aimed at relegating the Spanish Socialist Workers' Party (PSOE) into third place.

[22] More than one hundred intellectuals and artists, including El Gran Wyoming, Antonia San Juan, Carlos Bardem, Fernando Tejero, and Luis Tosar, signed a manifesto calling for Podemos, IU and their regional alliances to join forces for the coming election.

[25] Mayor of Barcelona Ada Colau, also voiced her support for such a pact stating "I would see as positive that it could be put together, always with respect",[26] her En Comú Podem regional alliance having already seen both parties working together in Catalonia.

[34] On 9 May 2016, Pablo Iglesias Turrión of Podemos and Alberto Garzón of IU officially announced an alliance between their respective parties,[35][36] with both leaders symbolically sealing their pact through an embrace at Puerta del Sol in Madrid, landmark of the 15-M movement.

[citation needed] In the April 2019 Spanish general election, the party lost 29 seats and fell to the 4th place in the Congress of Deputies, below Ciudadanos.

The founder and former leader of Podemos, Pablo Iglesias Turrión, wants Catalonia to continue as part of Spain, but says his party would respect the will of the 80% of Catalans who want a referendum according to polls.

It also included revoking or curtailing the Treaty of Lisbon, abandoning the memorandum of understanding, withdrawing from some free-trade area agreements, and promoting referendum on any major constitutional reform.
