Spain’s Prime Minister Pedro Sanchez pledged on Sunday to outlaw prostitution in the country.
Speaking to supporters at the end of his Socialist Party’s three-day congress in Valencia, Mr Sanchez said that the practice “enslaves” women.
Prostitution was decriminalised in Spain in 1995 and in 2016 the UN estimated the country’s sex industry was worth €3.7bn (£3.1bn, $4.2bn).
A 2009 survey found that up to 1 in 3 Spanish men had paid for sex.
However, another report published in 2009 suggested that the figure may be as high as 39% and a 2011 UN study cited Spain as the third biggest centre for prostitution in the world, behind Thailand and Puerto Rico.
