Teachers, parents, students and activists in this wealthy northeastern region have leapt into action to defend the vote slated for Sunday, defying Madrid's warnings of repercussions by occupying more than 160 schools designated as polling stations, it said.
The regional police force has been ordered not to use force in vacating the schools but Millo said anyone remaining after 6 a.m. will need to be removed.
The Election Monitoring Committee has been disbanded, and thousands of police officers have been deployed to block entry to the polls.
But, as has been mentioned, no can be sure what will happen if independence does come to the region.
If it does take place, and if the Catalan people vote "yes", Catalan leader Carles Puigdemont said they would declare their independence within 48 hours, Reuters reports. "If it gets complicated we'll stay inside peacefully and they won't move us". "Then, if "yes" or "no", it's up to each person".
Ryanair cancels more flights - affecting a further 400000 passengers
The low-priced carrier will then withdraw ten aircraft, from a planned fleet of 445, from April 2018. That will mean canceling 18,000 flights on which about 400,000 passengers have booked.
A minority of around 40 percent of Catalans support independence, polls show, although a majority want to hold a referendum on the issue.
Fernando Satue, 67, a retired mechanic who was born in Huesca and has lived in Catalonia since he was 5, said that the mounting demand for independence has made him apprehensive about expressing his opinions in public.
Catalonia, one of Spain's 17 autonomous regions, has some 7.5 million people and includes the tourist-popular Mediterranean port of Barcelona, the country's second-largest city, which is home to a Catalan parliament and regional government. A pro-unity crowd also gathered in Barcelona. It is unclear how Catalan police will behave.
The Catalan government appeared to soften its language somewhat in a news conference Saturday, with officials talking of "peaceful resistance" and a peaceful demonstration of people's democratic rights. Spain's Prime Minister, Mariano Rajoy, has said such a ballot would be invalid and in violation of Spain's constitution.
"I think it's about democracy and liberty", Ramon Hernández, 80, said. The tractors eventually stopped, converging on the regional government building.
FC Barcelona have not spoken out yet about the consequences of the nation's potential independence.
The possibility that Catalonia would split off from Spain is very much like California's "Calexit" movement.
