From today's (27 September 2016) print edition of the Spanish language El Periódico - both the front page and the double page spread on pages 28 and 29
This Spanish newspaper prints two editions - in Spanish and Catalan - seemingly with the exact same articles and layouts etc - according to Wikipedia it has a combined print circulation of both languages of around 125,000 making it the fifth biggest print circulation in Spain which has a population of around 46 million.
(actually, that print circulation figure seems rather low for the 5th largest circulation?)
The print edition includes a copy of the letter which you can read here:
