Sumar, a Spanish political party, is preparing for a crucial assembly in December to redefine its organizational and political strategies.

This comes after a challenging period marked by poor electoral results and internal dissatisfaction, leading to Yolanda Díaz stepping down from leadership.

The party is now led by a provisional team close to Díaz, who remains a key political figure.

The upcoming assembly aims to address major issues like labor reform, housing, and work-life balance, while also clarifying Sumar's relationship with other political forces.

The party's initial plans to integrate other leftist groups have shifted towards a more equal partnership model.

As Sumar navigates these changes, it faces the challenge of maintaining unity within the broader left-wing political space in Spain.
