Spain is one of the largest producers of fruits and vegetables in the world.

Cheap plastic greenhouses cover tens of thousands of hectares and migrant workers pick the fruits and vegetables that are sold in European supermarkets.
The BBC has spent several months investigating allegations of exploitation there.
