First Lady of Mexico

First Lady of Mexico (Spanish: Primera Dama de Mexico, Primera Dama de los Estados Unidos Mexicanos) is the unofficial title of the wife of the President of Mexico. The post is highly ceremonial and in fact once caused severe controversy when it was thought that the First Lady took too much involvement in their husband's post.

María Flores de Lascuráin, spouse of President Pedro Lascuráin, was Mexico and the world's briefest ever First Lady, since her husband served as president for less than an hour. However, since the title is not official in Mexico (unlike other Latin American countries), this fact is not actually acknowledged.
