Mexico's president on Tuesday proposed allowing same sex marriage nationally, the latest in a series of progressive policies in a traditionally conservative country.
The presidency said on Twitter that President Enrique Pena Nieto had "announced the signing of a reform initiative which includes the recognition of the right to get married without any form of discrimination."
Same sex marriage is currently permitted in Mexico City, as well as in several states including Coahuila, Quintana Roo, Jalisco, Nayarit, Chihuahua and Sonora.
Mexico's Supreme Court said last year that laws restricting marriage to a man and woman were unconstitutional and a Supreme Court judge urged states to legalize gay marriage.
However, many state legislatures have not changed their statutes to comply, meaning couples must file legal challenges case by case to get married. Gay marriage is still banned under local laws in many of Mexico's 31 states.
