In the context of a pivotal week for the left in Spain, Yolanda Díaz has addressed Prime Minister Sánchez with a message emphasizing his historical role. This week is underlined by efforts to reshape the left, particularly to the left of the PSOE, culminating in significant events that aim to unify and strategize as they seek momentum. One of these events features ERC spokesperson Gabriel Rufián and Más Madrid's Emilio Delgado, which is set for Saturday in Madrid.

While Unidas Podemos and other left-wing parties like Izquierda Unida, Más Madrid, and Comunes have confirmed participation in this reconfiguring process, IU has stated its intention not to attend the Rufián event due to the lack of a formal invitation, illustrating the complexities within the leftist factions. Despite clarifications that attendance is open to anyone, IU expressed an unwillingness to commit without an invitation, highlighting potential divides in strategies and alliances within the left.

The decision by IU and Podemos to step aside from this event raises questions about solidarity and the direction of leftist politics in Spain, especially as these factions work to forge a unified front against the governing PSOE. The varying responses to the event reflect the ongoing negotiations and sensitivities surrounding leftist unity, which will be crucial in the political landscape moving forward.
