MADRID/BARCELONA (Reuters) - Sacked Catalonian president Carles Puigdemont on Saturday called for peaceful  democratic opposition  to the central government s takeover of the region following its unilateral declaration of independence from Spain. Puigdemont, whose regional government was dismissed by Spanish Prime Minister Mariano Rajoy on Friday, accused Madrid of  premeditated aggression  against the will of the Catalans. Rajoy removed Puigdemont, took over the administration of the autonomous region and called a new election after Catalonia s parliament declared itself an independent nation on Friday. The bold if to all appearances futile action marked a potentially dangerous escalation of Spain s worst political crisis in the four decades since its return to democracy.  It s very clear that the best form of defending the gains made up until now is democratic opposition to Article 155,  Puigdemont said in a brief statement he read out in the Catalan city of Girona, referring to the legal trigger for the takeover. But he was vague on precisely what steps the secessionists would take as the national authorities are already moving into Barcelona and other parts of Catalonia to enforce control. Spanish government spokesman Inigo Mendez de Vigo said it  would welcome Puigdemont s participation in the regional elections it has called for Dec. 21.  I m quite sure that if Puigdemont takes part in these elections, he can exercise this democratic opposition,  Mendez de Vigo told Reuters TV in an interview. European countries, the United States and Mexico have rejected the Catalan declaration and expressed support for Spain s unity. Puigdemont signed the statement as President of Catalonia, demonstrating he did not accept his ousting.   We continue persevering in the only attitude that can make us winners. Without violence, without insults... and also respecting the protests of the Catalans who do not agree with what the parliamentary majority has decided,  he said. The secessionists say a referendum on Oct. 1 gave them a mandate for independence. However, less than half of eligible voters turned out for the ballot, which Madrid declared illegal and tried to stop. Opinion polls show that more than half of the 5.3 million people eligible to vote in the wealthy northeastern region, which is already autonomous, do not want to break from Spain.  But emotions are running high and the next few days will be tricky for Madrid as it embarks on enforcing direct rule.  Calling a new regional election is something of a gamble by  Prime Minister Mariano Rajoy as it could increase the numbers of pro-independence supporters in a new parliament. But Mendez de Vigo said it would give Catalans the final say about how they felt. Asked what would happen if Puigdemont had to face prosecution, Mendez de Vigo said judicial and political powers were separate in Spain and that  no one is above the law.  He did not comment further.   Catalonia s police force told its officers to stay neutral, a step towards averting possible conflict following doubts over how the Mossos d Esquadra, as they are called, would respond if ordered to evict Puigdemont and his government.  The force is riven by distrust between those for and against independence and also estranged from Spain s national police forces, Mossos and national officers have told Reuters. Some Catalan officers stood between national police and those trying to vote during the referendum.   Given that there is it is likely to be an increase in gatherings and rallies of citizens... and that there are people of different thoughts, we must remember that it is our responsibility to guarantee the security of all and help these to take place without incident,  an internal memo said. Government buildings, the headquarters of national political parties, ports, airports, courts, and the Bank of Spain were being guarded, the Interior Ministry said. Units of the regional force could be replaced if events made that necessary, it said. The Madrid government also sacked the Mossos  chief, Josep Lluis Trapero, who became a hero to the secessionists after his force took a much softer stance than national police in enforcing the referendum ban. Spain s High Court barred Trapero from leaving the country and seized his passport as part of an investigation for alleged sedition, although it has not ordered his arrest.  In Barcelona, thousands of independence supporters packed the Sant Jaume Square in front of the regional headquarters on Friday night, waving Catalan flags and singing traditional songs in the Catalan language as bands played. But there was no trouble overnight and the streets were quiet on Saturday.  The main secessionist group, the Catalan National Assembly, has urged civil servants not to follow orders from the Spanish government and to mount  peaceful resistance  while a pro-independence trade union, the CSC, called a strike. The government said it would ensure a minimum service. About 1,000 people took part in a pro-unity rally in Madrid on Saturday and others turned out in the northern city of Valladolid   an indication of the resentment the independence drive has caused in the rest of Spain. Aitor Sanchez, a 30-year-old worker, said he was saddened  the government had taken control of Catalonia but it had no choice.  These are delicate moments in our country. But I believe we must respect the law.  The chaos has prompted an exodus of businesses from Catalonia, which contributes about a fifth of Spain s economy, the fourth-largest in the euro zone. Tourism in hugely popular Barcelona has been hit, and markets have shown signs of concern. European leaders have also denounced the push, fearing it could fan separatist sentiment around the continent.
