Over the past few weeks, Catalan leaders have been firmly committed to their promise of a declaration of independence if a "yes" vote wins at this Sunday's October 1 "referendum", despite the increasing logistical problems the vote is facing after Spain's Constitutional Court suspended regional referendum and secession laws passed at the beginning of September.

Prosecutors and police have acted in an ongoing series of operations to seize ballot papers and election materials, and to shut down website and mirrors promoting the vote.

The referendum and secession laws state that the Catalan Parliament will declare independence within 48 hours of a "yes" vote on Sunday, with a simple majority and no minimum turnout rate.

Catalan First Minister Carles Puigdemont repeated in a TV interview—recorded last Friday but broadcast on Sunday—that he was ready to go that far next week if separatists won their vote.

On Tuesday, however, Catalan government spokesman Jordi Turull said during a press conference that any declaration of independence would be a job for the regional parliament.

"Our job as the government ends on October 2", he said: "After that, parliament will take the decision", adding that "the only plan is to vote on October 1, the government doesn't want to get into anything else at the minute".

In Brussels on Tuesday afternoon, the Speaker of the Catalan Parliament, Carme Forcadell, passed the buck back to Mr. Turull.

"That is a decision that corresponds to the government", she said: "I represent the parliament".

On Tuesday morning, a spokesman in the Spanish Congress for PDeCAT, the party that Mr. Puigdemont and Mr. Turull belong to and half of the governing coalition in Catalonia, Junts Pel Sí, said there would be no declaration of independence at all.

Carles Campuzano said that move had been "absolutely ruled out" and said it was time for dialogue with the central government: "what needs to happen is to let Catalans vote and, then, listen and start to talk".
