The full collision between Madrid and Barcelona is underway as the Spanish Senate braces for a vote that will suspend the Catalan devolved administration on Friday.

On Monday, Barcelona warned of active resistance to direct rule by Catalan members of the public administration, including the police. The anti-capitalist CUP that supports the Catalan government is also calling for mass “civil disobedience.”

 “It is not a personal decision. It is the personal decision of seven million people,” Catalonia’s foreign affairs chief Raul Romeva told BBC radio.

Meanwhile, according to Reuters, the Catalan President Carles Puigdemont is considering appearing before the Spanish Senate committee on Thursday to make the case against suspending autonomy.

Suspending Catalan autonomy is now supported by three of the four national parties, including the ruling Popular Party, the Spanish Socialists (PSOE), and the Liberal Ciudadanos. Although 90% of those who voted on the October 1st referendum back independence, only 43% of registered voters went to the polls.

 However, PSOE has made clear that they are willing to back off from invoking article 155 of the Spanish Constitution if Puigdemont returns to “rule of law.”

Catalan authorities are planning a plenary session of the regional parliament on Thursday and Friday to debate “the liquidation” of self-rule. The question is whether the crisis will escalate by the declaration of independence triggering the arrest of the Catalan government.
