The Spanish ambassador to UK has warned of 'drama for Europe' if Catalan's independence vote goes forward, as thousands march in Barcelona over the 'illegal' independence referendum.
Carlos Bastarreche, the Spanish ambassador to UK has called the referendum a 'coup d'etat' explaining that an independence result will have a long lasting affect on European stability and reignite Scottish separatism.
The Spanish government considers the referendum illegal, the country's Constitutional Court having suspended it more than three weeks ago.
But regional separatists have vowed to go ahead with balloting, occupying at least 160 schools throughout the weekend so that they can be used as polling stations for tomorrow's disputed vote.

The Catalan police force are under orders to empty the buildings by Sunday at 6am.
Meanwhile thousands of Catalans are marching in downtown Barcelona and Madrid in defence of Spanish unity, demanding that Catalan leaders be sent to jail.
Protesters wrapped in red and yellow - regional and national colours - chanting, 'Don't let them fool you, Catalonia is Spain', amid calls for regional president Carles Puigdemont to step down.
Mr Puigdemont, 54, openly favours the autonomous regions break from Spain, which is a crucial to contributor to the country's economy.
On Saturday Mr Puigdemont said he and his supporters would not 'give up' their rights, describing Madrid's attempts to ban the referendum as 'authoritarian repression' and 'the fall of democracy'.
In an interview with AFP he insisted that his government had 'everything in place so that everything takes place normally'.
There are 5.3million registered voters but Mr Puigdemont has been criticized for not being able to explain what a Catalan independence would look like.
In an interview with the Associated Press, Foreign Minister Alfonso Dastis accused the Catalan government of trying to promote an exclusionary system that runs counter to the goals and ideals of the European Union.
Mr Dastis said the radical CUP party, which shores up Catalonia's separatist-minded government, was 'adopting Nazi-like attitudes by pointing at people that are against that referendum and encouraging others to harass them.'
He defended the Spanish government's decision as 'totally justified' to deploy thousands of police reinforcements to Catalonia to prevent the vote.

He said the CUP had put 'out posters with the faces of mayors who are not supporting the referendum' - comparing that the Nazis' use of posters and signs to single out the houses of Jews.
Dastis also criticized the use of children this weekend to occupy schools in Catalonia so that they can be used as polling stations. Parents and pupils were occupying the schools so police could not dismantle polling stations in them.
The Spanish government has said that most potential voting stations for the banned Catalan referendum have now been closed.

2.3 million people voted in a mock referendum in 2014, in which 80% favoured independence.
Catalan National Assembly, the main civic group behind Catalonia's push for independence, says a turnout of 1million voters - less than a fifth of the electorate - would make the region's secession referendum an 'overwhelming success' given the Spanish government's efforts to stop the vote.
The Catalan government has pledged to declare independence from Spain within 48 hours of Sunday if the 'yes' vote wins, no matter what the turnout is.
Calls for secession have grown as austerity has risen.
Around 4,000 state police from other regions have been deployed to prevent the vote and maintain security. They will join 5,000 state police based in the region and 17,000 local police, or Mossos d'Esquadra

The fight for Catalan independence
More than 2,300 polling stations are ready for the Catalan independence referendum slated for Sunday but banned by Madrid, the regional separatist government said today.
Spokesman Jordi Turull told reporters there would be '2,315 polling stations all over the region' and more than 7,200 people involved in holding the referendum despite a crackdown by Madrid.
'A total of 5.3 million Catalans who have the right to vote are called to vote,' he said.
At the end of the press briefing, Turull, Catalan Vice-President Oriol Junqueras and Raul Romeva, in charge of foreign relations for the Catalan executive, unveiled a plastic ballot box with a regional government stamp on it.
Police have for days been seizing electoral items such as ballot papers as they follow orders to stop the referendum from taking place, after courts ruled it unconstitutional.
But they had failed to find any ballot boxes until Thursday, when police seized 100 from a warehouse in a Catalan town, although the company in charge alleged they were destined for internal elections at the FC Barcelona football club.
Over the past few days, judges and prosecutors have also ordered the closure of websites linked to the vote and the detention of key members of the team organising the referendum.
On Wednesday a judge ordered police to prevent public buildings from being used as polling stations.
