The law will allow children 12 years old and up to change the sex on their ID cards.

The legislation was passed on December 22 in a 188-150 vote and will now have to go through the Senate to be approved, according to a BBC report 

The left-wing Podemos party, which is part of Spain’s government coalition, was the driving force behind the transgender bill. The Podemos party’s Equality Minister, Irene Montero, said that the legislation “de-pathologizes gender-confused persons and guarantees their “rights.”
