Millions of people were left without power after a massive blackout hit mainland Spain on Monday, bringing transport services and businesses to a halt.
Towns and cities across mainland Spain were affected by the massive outage which hit at around 12.30pm on Monday.
The cause of the blackout is still under investigation and authorities say it is likely to take up to 10 hours to restore the power to all regions.
