Tensions between Mexico and Spain have resurfaced as Spain decides not to send official representation to the inauguration of Mexico's first female president, Claudia Sheinbaum, on October 1. This decision follows a diplomatic rift that began in 2019 when Mexican President Andrés Manuel López Obrador requested an apology from Spain for historical grievances dating back to the Conquest.

The Spanish government, led by Pedro Sánchez, firmly rejected this request, leading to a cooling of relations.

The absence of an invitation to King Felipe VI for Sheinbaum's inauguration has been perceived as a continuation of this diplomatic strain.

While Spain's government and the opposition party PP support the decision to not attend, some coalition partners express discomfort, highlighting internal political tensions.

Despite these diplomatic challenges, both nations maintain strong cultural and economic ties, with over 20,000 Spaniards residing in Mexico.
