Lopez believes that prostitution is an important part of the country's tourism economy. "Prostitution moves a huge amount of money in summer." she told the Daily.
"Just as they regulate hotels and restaurants to make sure all the workers are registered, they should also see that the girls are comfortable and legalised."

While prostitution remains legal in Spain, local governments such as Barcelona and Madrid have moved to limits its practice and others think that regulation is set to increase.
Gloria Poyatos, a former employment lawyer who has advised prostitutes in Ibiza told news agency AFP "I think that something is changing. A debate in society is beginning on whether or not to regulate prostitution."
