[15][16] After the crisis sparked in January 2019 by Íñigo Errejón's announcement to form a tandem with Carmena ahead of the 2019 Madrilenian regional election, the platform threatened to cause a major split in Podemos in the Community of Madrid.

This clashed with attempts from Podemos and United Left–Madrid to impose party member quotas in the lists, bringing a number of outsider partisan figures in place of Carmena's allies.

[20][21] On 12 November 2018, all Podemos members in the City Council of Madrid (Rita Maestre, José Manuel Calvo, Jorge Castaño, Esther Gómez, Marta Gómez Lahoz, and Paco Pérez) chose to withdraw from the party's scheduled primary election in the city and instead announced their intention to contest the municipal election within Carmena's planned platform as independents, prompting Podemos to suspend them from party membership.

[30][31] Podemos leaders also urged Errejón to resign his seat in the Congress of Deputies,[32] considering his move as "deceitful" and "a betrayal" of the party.

[36] Some media outlets, such as El Confidencial, had tentatively predicted at first that Más Madrid would become a grouping of electors, as it aimed to distance itself from the umbrella of any political party.

"[11] On 10 March 2022, the Constitutional Court of Spain supported to the complaint filed by Más Madrid after the 2021 elections, in which the party was excluded from the Bureau of the Madrid Assembly despite having obtained 15% of the votes in favor of Vox, which obtained 8% of the votes, establishing that article 23.2 of the Constitution was violated as the "right of access to the position under conditions of equality was violated in this case due to the lack of proportionality of the agreement reached, which left a party (Más Madrid) that had obtained almost double the percentage of votes out of the Parliament's management body than another that did achieve a position (Vox)".
