CatalanleaderCarles Puigdemont came underpressure from one of his key allieson Friday todeclarefullindependenceandignorea threat of direct rule from the Spanish government.
Puigdemont made a symbolic declaration ofindependenceon Tuesday night, only to suspend it seconds later and call for negotiations withMadrid.
Spain's Prime Minister Mariano Rajoy has given him until Monday to clarify his position - and then until Thursday to change his mind if he insists on a split - threatening to suspend Catalonia's autonomy if he choosesindependence.
But far-leftCatalanpolitical group CUP called on Puigdemont to make an unequivocal declaration ofindependencein defiance of thedeadlines.
"If (the centralMadridgovernment) wants to continue to threaten and gag us, they should do it to the Republic that has already been claimed," the party said.
The CUP only holds 10 seats in the 135-seatCatalanparliament. But Puigdemont's minority government relies on its support to push through legislation and cannot win a majority vote in the regional parliament without its backing.
The wealthy region's intention to break away after a referendum has plunged Spain into its worst political crisis since an attempted military coup in 1981.
Sources close to theCatalangovernment said Puigdemont and his team were working on an answer to Rajoy though they declined to say what line he might take.
The CUP statement echoes the position expressed late on Thursday by influential pro-independencecivic group Asamblea NacionalCatalana which said: "Given the negative position of Spain toward dialogue, we ask the regional parliament to raise the suspension (on the declaration ofindependence)."
But theleaderof Puigdemont's party, Artur Mas, who served as the region's president until 2016 and is still believed to influence key decisions, said on Friday declaringindependencewas not the only way forward.
"If a state proclaims itself independent and cannot act as such, it's anindependencethat is merely aesthetic," he toldCatalantelevision TV3.
"The external factor must be taken into account in the decisions that will be made from now on," he said.
The European Union, the United States and most other world powers have made it clear they wanted Catalonia to remain within Spain.
"If we allow Catalonia - and it is none of our business - to separate, others will do the same. I do not want that," Jean Claude Juncker said in a speech at Luxembourg University.
