Catalonia crisis: Madrid prepared to discipline Catalans

"The Spanish government is going to have the responsibility of taking decisions of a disciplinary nature if there is a rejection, by any functionaries, of any of the orders that they receive," Enric Millo told CNBC on Monday, according to a translation.

Prime Minister Mariano Rajoy invoked unprecedented constitutional powers on Saturday, vowing to curtail some of the freedoms of Catalonia's parliament, sack some of its political players and force regional elections within six months. A vote in the national Senate to implement this direct rule is scheduled for Friday.
