Spain's minority left-wing government wants to galvanise its deadlocked 2025 draft budget by linking it to urgent reconstruction funds following devastating floods, sparking "blackmail" accusations from the conservative opposition.

Spanish Prime Minister Pedro Sanchez announced a new economic relief package for victims of the storms that killed more than 220 people in the country’s worst natural disaster in more than six decades.

The announced assistance for flood ravaged regions comes amid mounting criticism. Sanchez has compared the move to Spain's efforts during the coronavirus pandemic.

The political reckoning over Spain's deadliest floods in decades must wait until after the country recovers from the disaster, which triggered widespread anger at the governing class, Prime Minister Pedro Sanchez said on Monday.
