After a party crisis in January 2019, following the announcement of Íñigo Errejón vowing to run as candidate for the 2019 Madrilenian regional election within the Más Madrid platform, Espinar renounced to his parliamentary seat at the regional legislature (and therefore also to his seat as senator) as well as handed in his resignation as leader of Podemos in the Community of Madrid and the rest of his roles at the party, arguing the conditions to carry the Podemos project in Madrid towards where he thought it should be driven towards were not there.
