What's going on in Catalonia now?
The vote has also been branded illegal as Catalonia's political leaders did not follow due political process to call the referendum, according to the Spanish government. The Catalan government said that around 2.26 million of the region's 5.34 million voters were able to cast their vote on Sunday. Barcelona's port was at a standstill.
"These are times for unity and stability", he said. Spokesman Jordi Turull described King Felipe's intervention as a gravely irresponsible act that "puts more logs on the fire".
Catalonia is a wealthy region of some 7.5 million people in northeastern Spain, with its own language and culture.
How would that go down?
Spain national team manager Julen Lopetegui has highlighted Gerard Pique's "exceptional" behaviour following his recent offer of international resignation.
The violent response of Spanish authorities to the referendum - broadcast worldwide with images of police using rubber bullets and batons on voters - has prompted discomfort internationally and fury in Catalonia.
The Liga game at Camp Nou was played behind closed doors, with Bartomeu stating Barca had been told by the Liga de Futbol Profesional (LFP) they would be docked six points if they refused to play. "Today, we are closer to independence than we were a month ago".
Madrid says it will not formally recognise an independence declaration, reports The Guardian.
Felipe placed the blame for the tension firmly in the hands of the Catalan regional authorities said they "in a repeated, conscious and deliberate manner, have been breaking the Constitution and their Autonomous Status".
The region's leaders defied Madrid by holding a banned referendum on independence on Sunday.
Metro stations were deserted as services were cut back sharply, pickets blocked traffic on Gran Via street, and traffic on six major highways in the region was disrupted by protests.
"Catalan banks are Spanish banks and European banks are solid and their clients have nothing to fear", Luis de Guindos, Spain's Economy Minister said Wednesday.
