In a surprising political maneuver, Spain's Sumar party has aligned with the opposition Popular Party (PP) to advance legislative proposals in Congress, causing a rift with their coalition partner, the PSOE.

The agreement allowed the PP's proposal, which mandates parliamentary approval for military missions abroad, to progress, despite PSOE's opposition.

In return, the PP supported Sumar's initiative to address abusive mortgage clauses.

This collaboration marks a strategic move by Sumar to explore future cooperation with the PP on social issues, such as reducing work hours and improving work-life balance, aligning with PP's recent 'social shift.

' The PSOE, however, remains wary of this new alliance, particularly concerning military policy, a sensitive topic within the coalition.
