Article 80 of the Mexican Constitution reads: “Se deposita el ejercicio del Supremo Poder Ejecutivo de la Unión en un solo individuo, que se denominará ‘Presidente de los Estados Unidos Mexicanos'” (The exercise of the Supreme Executive Power of the Union is vested in a single individual, who shall be called “President of the United Mexican States”). The article has kept its original wording since the Constitution was published in February 1917.
