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.
