Más Madrid has reached a pact with Sumar in which Yolanda Díaz recognizes her role as the hegemonic force of the political space of the alternative left of the PSOE in the region. The party led by Monica Garcia will have half of the starting positions on the constituency list, in addition to being able to co-direct the campaign.

In this way, Más Madrid ensures a preponderant role in the electoral list that has given the most headaches to the negotiators of Sumar.
