A Spanish government official Friday offered the first apology to Catalans injured by police during their outlawed independence vote as the sides showed tentative signs of seeking to defuse the crisis.

Catalan leaders had threatened to declare independence unilaterally and Prime Minister Mariano Rajoy vowed to stop them, rejecting calls for mediation in a dispute that has drawn cries of concern even from Barcelona and Real Madrid footballers.

Spain’s deepest political crisis in decades has raised fears of further unrest in the northeastern region, a tourist-friendly land of 7.5 million people that accounts for a fifth of Spain’s economy.

Friday saw the first signs the sides may be willing to step back from the brink in a political conflict that risks destabilising Europe.

After days of ill-tempered rhetoric, the central government said it regretted the injuries and suggested Catalonia should hold a regional election to settle the crisis.

Catalan government minister Santi Vila, a close of ally of regional president Carles Puigdemont, meanwhile told broadcaster Rac1 that his side could consider a "ceasefire” in the dispute, to avoid a further crackdown by Madrid.

Businesses and the government kept up economic pressure on Catalonia however, with several big companies announcing moves to shift their legal domiciles to other parts of Spain.

‘We deeply regret’

Puigdemont postponed an appearance in the regional parliament at which some leaders were hoping for a declaration of independence, a spokesman said -- gaining time and easing tensions. It was unclear what he planned to say at the session.

Spain’s central government apologised on behalf of police to people hurt in last Sunday’s referendum disturbances.

"I can do nothing but regret it, apologise on behalf of the officers who intervened,” said the government’s representative in Catalonia, Enric Millo.

"I am very sad, very sorry, we deeply regret that we have arrived at this situation,” he said.

Central government spokesman Ignacio Mendez de Vigo also said later he "regretted” the injuries.

"It would be good to start mending this fracture... through regional elections,” he told a news conference.

‘Sedition’ claims

In Madrid meanwhile, Catalonia’s police chief and two prominent separatist leaders avoided being remanded in custody at a court hearing Friday over sedition accusations.

The court summons raised tensions, but despite the gravity of the accusations the court did not issue a custodial order that could have further escalated the dispute.

Jordi Cuixart and Jordi Sanchez, leaders of Catalonia’s two biggest pro-independence civil groups, and regional police chief Josep Lluis Trapero walked free from the preliminary hearing at the National Court in Madrid.

The two civil leaders were accused of sedition for their role in unrest during protests in Barcelona last month.

Trapero’s force was accused of failing to rein in the protesters.

Economic pressure

Spain’s Constitutional Court on Thursday ordered the suspension of a session scheduled for Monday in the Catalan parliament at which some leaders have called for an independence declaration.

If Catalonia declares independence, Spain could respond by suspending the region’s existing autonomous status and imposing direct rule from Madrid.

On another front, the government in Madrid pushed ahead with a measure to pressure Catalonia economically.

It passed a decree to make it quicker for businesses to shift their legal domiciles away from one region to another.

Energy company Gas Natural and Catalonia’s two biggest banks, Sabadell and CaixaBank, said they were shifting their legal headquarters out of Catalonia.

Sources who asked not to be named told AFP that some customers had been withdrawing money from their bank accounts over concerns for the political situation.

With its own language and cultural traditions, demands for independence in Catalonia date back centuries but have surged during recent years of economic crisis.

Region split

The Catalan government later on Friday published final results from the referendum vote indicating that 90 percent of voters backed the region breaking away from Spain.

Voter turnout was 43 percent.

Recent polls have indicated that Catalans are split on independence, though leaders warned the violence during the referendum turned many against the state authorities.

Switzerland said Friday it was "in contact” with both sides in the crisis but stressed that formal mediation could not begin until both camps were ready.

Madrid has said there will be no talks or mediation until the Catalans abandon the independence bid.
