Spain and Mexico: What's behind the diplomatic conflict?

On the 12th of October, Spain will be celebrating it National Day, which includes several commemoratory events and a military parade presided by King Felipe VI. This day commemorates Christopher Columbus' arrival to the Americas, an issue that has been quite controversial, particularly in the last few weeks, after newly elected Mexican president, Claudia Sheinbaum, brought up a letter sent by her predecesor, Andrés López Obrador, to the Spanish King asking for an apology for the acts committed during the conquest. 

On this broadcast, we analyze the consequences and origin of this request, as well as Spain's historical relations with Mexico, with historian and professor in the Universidad Autónoma of Madrid, Manuel Burón.
