HUNDREDS of thousands of people packed the streets of Barcelona yesterday to call for Catalonia to break away from Spain, two weeks before a regional election that many see as a “make-or-break” moment for the independence movement.

Around 500,000 people had registered to dress in white and form a white “human mosaic” symbolising a blank page and the new country they hope to build after the September 27 election. At least one and half million are estimated to have attended.

At 17:14 local time, on Catalonia’s ‘national’ day, in remembrance of the defeat of Catalan forces on September 11, 1714, at the hands of Philip V of Spain, the 5km “mosaic” in the Meridiana Avenue erupted with colour as people raised separatist flags as well as banners declaring “Ara es l’hora” – “It’s time”.

Catalonia’s independence movement has long been associated with that of Scotland and the vote in Spain comes just over a week after marches will be held across Scotland to commemorate the anniversary of last year’s referendum – and to campaign for the next one.

Silvia Palomares, a 48-year-old interior designer from Barcelona, said this year’s celebrations were more important than those before.

“This is the definitive year,” she said. “If we don’t manage to have people going to vote on the 27th, then we’ll suffer. The goal is to become independent, because we’re suffocating – economically and emotionally.”

A closely watched survey on Thursday suggested that separatist parties would achieve the slimmest of majorities in the regional parliament, but fall well short of 50 per cent of the vote.

While any outcome, positive or negative, will shape Spain’s political agenda before a December general election, a separatist victory would be unlikely to translate into outright secession.

Pro-independence parties have said they will start a “road map” to an independent Catalan state within 18 months if they win control of the regional assembly.

“After many centuries, we have the great opportunity to vote on our democratic future, so we have to take advantage of this occasion. Only a clear ‘Yes’ can change things,” said Artur Mas, the head of the regional government.

“If we don’t have this ‘Yes’, it won’t be possible to go on with this political process with the same energy and intensity.”

Spain’s centre-right prime minister, Mariano Rajoy, opposes both the attempts to turn the Catalan election into a proxy vote on independence and the idea of secession itself, which he has called a “nonsense”.

His government, which went to court last year to block a referendum on Catalan secession, has tabled a bill for an urgent reform of Spain’s constitutional court that would give it enough clout to stop any unilateral declaration of independence.

However, with pollsters predicting the regional election would leave the Catalan parliament divided and fragmented, it may simply extend a deadlock between local and national authorities.

Several national parties have said they are ready to discuss a constitutional accommodation for Catalonia after the general election, but it would require a broad consensus that will be hard to reach.
