The leader of the Spanish People´s Party and current Prime Minister of Spain Mariano Rajoy has always been emphasizing in his speeches that the Spaniards should show with frankness their pride to be some Spaniards.
See for this for example an article of October 11, 2007 titled “Rajoy pide a los ciudadanos que manifiesten ‘con franqueza’ su orgullo de ser españoles” in the Spanish newspaper “El Mundo“. October 12 is the national day of Spain.
Now: The Puerta del Sol (Spanish for “Gate of the Sun“) is one of the best known and busiest places in Madrid. This square is the centre (Km 0) of the radial network of Spanish roads and also contains the famous clock whose bells mark the traditional eating of the Twelve Grapes and the beginning of a new year. The New Year’s celebration has been broadcast live on national television since December 31, 1962.
But on June 1, 2013 this subway station has been renamed now “Estación Vodafone Sol“.
So the name of the subway station of the probably most famous and most visited square in Madrid can be bought for some euros now by some British telecommunications company.
Well, if you can buy something like that for some euros here, there are probably a lot of other things too you can buy now in Madrid for some euros.
And there is a famous latin saying: “Pecunia non olet” (in English: “Money doesn´t stink“).
So I don´t believe that the politicians for example of the “Partido Popular” (headed in Madrid by the current Mayor of Madrid Ana Botella) who sold the name of the subway station of the most famous and most visited place of the Spanish capital will be very picky about what they are willing to sell or to offer and about what kind of corporations, organizations or private persons wanna make business here.
