Several Spanish news outlets have in recent days released leaked recordings from a German aristocrat said to have dated King Juan Carlos.
Corinna Larsen Adkins, also known as Corinna zu Sayn-Wittgenstein-Sayn, has for years caused controversy in Spain and helped lead to Don Juan Carlos’ abdication.
Now, recordings from 2015 leaked by a disgraced businessman and former commissar, suggest the King used her as a figurehead for properties.
Leftist parties have called for an investigation of King Juan Carlos, but so far major parties and news outlets have given the issue scant or no attention.

King Felipe and Queen Letizia went into what has become hostile territory late last week to hand out the Princess of Girona Awards.
Girona is a region is Spain, in Catalonia, with a relatively high rate of pro-independence sentiment.
Girona officials denied the King and Queen use of an arena there, citing repairs, and Catalan officials did not attend.
