Spains king felipe vi renounces fathers inheritance

I think there may be some confusion here!

King Felipe VI of Spain has not renounced his father's inheritance. In fact, he is the current King of Spain and has been since 2014, following the abdication of his father, King Juan Carlos I.

King Juan Carlos I was the King of Spain from 1975 to 2014, and he passed away on June 2, 2021. King Felipe VI is his son and heir, and he has continued to serve as the monarch of Spain since his father's abdication.

It's possible that you may be thinking of a different monarch or a different situation. If you could provide more context or clarify what you mean by "renounces his father's inheritance", I'd be happy to try and help you further!
