Iñaki Gabilondo, a well-known and respected Spanish political journalist, has spoken asking the King to abdicate. He has a videoblog in El Pais, so he has spoken there and there is no transcription.
Sorry, but it´s to long to translate, I´ll do it later if I have time. I´ll leave the video for those who speak Spanish, because I find it very interesting.
Iñaki is IMO a very good journalist. I don´t agree with everything what he says, but he states the facts very nicely and coherently, which is appreciated. And the title of the article says it all:
"My Crown, or THE Crown"
O mi corona o la corona >> La voz de Iñaki Gabilondo >> Videoblog Política EL PAÍS
EDIT: I´ve write a summary, because I know that at least An Ard Ri reads them
-"With Revenga´s imputation, and with the trial approaching Infanta Cristina,King´s Juan Carlos´ reign is reeling, and time is not in his favour".
-"In the streets, reproaches growns and society is tired."
-"I have the impression that, depite the very delicate moment we are living, King Juan Carlos will have to choose between his reign and the Monarchy, because his reign has no longer future. Monarchy still can have it, if the chapter is changed at time."
-"Don Juan Carlos will have to do something similar to what his father, Don Juan, did, step aside, for the institution that they defend can have a future"
-"The King shouldn´t make a mistake, he enjoys the affection of most of the people, according to the polls, but that affection can be used to make the relief on a respected way, but it can´t be used to continue, because in my opinion he can´t continue for now on".
-"In my opinion, what the Crown must do righ now is preparing the relief as fast as possible, because time is not in his favour".
