Throughout the day picket lines were present at railway stations, outside offices and across roads while protests were carried out in squares across Spain.

Spain's two main unions -- the CCOO and UGT -- were not part of the grouping that called the 24-hour strike but asked their members to stop work for just two hours on Thursday.

They estimated that 5.9 million men and women had observed the short stoppage.

Women hung aprons on their balconies in a pre-arranged sign they were ditching domestic chores for the day.

Feminist groups also called on women not to spend money, particularly on items such as deodorant whose versions created for women often cost more.   

In the evening huge demonstrations were called in towns and cities across Spain with an estimated 120 different marches taking place.

In Madrid, the streets were crammed with people wearing shades of purple as they marched between Atocha and Plaza Espana. Organisers claimed that close to a million joined the demonstration.

Here are some of the best shots from the protests.
