The Spanish government has taken recourse to the now infamous Article 155, and has gone way beyond its scope by removing the Catalan Government, dissolving the democratically elected Parliament, the seat of the representation of the Catalan people's sovereignty, and calling elections, the faculty of which is solely in the hands of the President of Catalonia, as elected by the Parliament.
The former are those who have led the Catalan Government and Parliamentary majority to take such measures as they have just to give voice to the citizens of Catalonia in a referendum, while the Spanish reaction was to send in riot police to aggressively repress a totally peaceful democratic vote attacking citizens who showed no violence whatsoever. Such is the attitude of Spain's so called Constitutional Bloc, that which approved the application of Article 155 in the Spanish Senate authorising the dissolution of a democratically elected Parliament and the Government it had endorsed.
And what if the latter win? What if the resulting Parliament once again shows a pro-independence majority, as the latest poll by a clearly pro-Spanish nationalist digital newspaper, El Español, countenances? Not a problem for the Senate's deputy speaker, Pedro Sanz, who stated in also pro-Spanish nationalist La Razón that if an outlaw (sic) majority wins they will apply Article 155 once again.
You can be pro-independence in "democratic" Spain, but you cannot be independent!
