Mexican Deputy Foreign Minister Martha Delgado is resigning from her post, she said on Twitter Tuesday, to begin "personal and political projects which require (her) complete attention."
In a letter of resignation addressed to Foreign Minister Marcelo Ebrard, Delgado thanked Ebrard and Mexican President Andres Manuel Lopez Obrador for her almost-five years in the role, but did not give further explanation as to her departure.
Ebrard told journalists Tuesday that Delgado had said she was leaving to promote his "aspirations." Ebrard has said he intends to run in next year's presidential election.
