The political landscape in Spain is experiencing significant turmoil as divisions deepen within the left-wing coalition Sumar over a controversial financing agreement between the PSC and ERC aimed at supporting Salvador Illa's presidency in Catalonia.

Carlos Martín, Sumar's economic spokesperson, has publicly criticized the deal, arguing it jeopardizes fiscal autonomy and promotes inequality among regions.

His stance contrasts sharply with the official support from Sumar's leadership, including Yolanda Díaz, who views the agreement as a positive step for Catalonia's relationship with Spain.

This internal conflict highlights the growing rift within Sumar, as various factions, including Compromís and Chunta Aragonesista, express their opposition to the deal, fearing it undermines solidarity among territories.

As the debate unfolds, the future of the financing model remains uncertain, with potential implications for the broader coalition government.
