The inauguration of López Obrador included only an invitation to Felipe VI, without including Queen Letizia, which represented an unusual discourtesy in Mexican protocol. This event left the regime in an uncomfortable position, activating its media machinery to attack Mexican former presidents residing in Spain who chose to change their residence.
López Obrador's wife, who played a leading role during his term, opted to remain silent. This situation created tensions that President Claudia Sheinbaum inherited by not inviting the King of Spain to her inauguration, despite his status as the head of the Spanish State.
The dispute between Mexico and Spain was aggravated by a letter sent by López Obrador to Felipe VI in 2019, asking for apologies to the Indigenous peoples of Mexico for the events that occurred during the Conquest. This letter, influenced by Gutiérrez Müller, was rejected by the Spanish government, generating tensions at the international level.
Gutiérrez Müller was involved in similar controversies, such as her alleged request for Spanish nationality, which caused uproar and criticism for her hostile actions towards Spain while apparently seeking to obtain this status. Through her influence in government decisions and public policies, Gutiérrez Müller has generated controversies and diplomatic tensions.
