MADRID: After simmering below the surface for years, anger at unaffordable housing in Spain has bubbled over and precipitated a general election that will be dominated by the crisis.

The spark was ignited on Sept 23 when 87-year-old Maricarmen Abascal was evicted from her lifelong Madrid home on a stretcher after the real estate firm that owned the apartment drastically hiked the rent.

Abascal, who died on Wednesday, became the symbol of a crisis that cuts across Spanish society: young and old, renters and buyers, workers and pensioners.

The uproar at her eviction triggered national demonstrations, with hundreds of people camping in central Madrid's Puerta del Sol square in the most symbolic protest.
