BARCELONA Spain (Reuters) - Hundreds of thousands of Catalans were expected to throng the streets of Barcelona on Thursday to demand the right to vote on a split from Spain, with their ambitions boosted by an independence referendum scheduled for next week in Scotland.
About half a million Catalans have signed up to dress in red and yellow, the colors of the Catalan flag, to form a "V" for "vote", organizers say, a show of support for the perceived right to decide on a status separate from Spain.
"We want a say in politics and our future. We've won back our sovereignty (by getting independence on the political agenda) and realized the strength we have, if we mobilize, to change things," said Carme Forcadell, head of the National Catalan Assembly (ANC), one of the organizers of the event.
Catalonia is a wealthy region in Spain's northeast with its own language and culture. Its long-standing independence movement has grown significantly over the last decade, exacerbated by Spain's economic crisis and what many see as a deaf-ears tactic by the Spanish government in Madrid.
The Catalan regional government, which like other Spanish regions has a large degree of autonomy, has called a referendum on Nov. 9 over whether to separate. But the Madrid government says the vote is illegal and cannot go ahead.
Polls show that 80 percent of Catalans want to vote on the issue.

The government in London opposes Scottish independence, but says it will abide by whatever the voters decide.
The fact that Scots have been allowed to vote at all was singled out as the main motivation for taking part in Thursday's event, organizers and participants said.
"We want to decide our future. We don't understand why that is constantly denied. We look up to Scotland," said Victor Panyella, a 50-year-old professor who was wearing a yellow t-shirt with a red "V" on it.
"They are so lucky to belong to a country that allows that kind of vote."
Artur Mas, head of the Catalan regional government, told reporters the rest of Spain needed to take heed.
"I ask Spain's institutions and especially its government to take good note of the mood on Catalonia's streets," he said.
"What is going on today is not a challenge to the state, it is the clamor of a large part of Catalan society."
An official Catalan opinion poll shows support for an independent state has tripled to 45.2 percent in March 2014 from 13.9 percent in March 2006. Many commentators in Madrid, where there is fierce opposition to Catalan nationalism, question the way such polls are carried out, however.
Spain's state pollster CIS found this year that around 45 percent of Catalans support full independence, 20 percent would support a federal state and 23 percent back an autonomous region.
"It would be the people's victory if we were allowed to vote. If we live in a democracy we should be allowed to vote," said Montserrat, a 58-year-old homemaker.
She said the most important issue was permitting the vote itself, not just whether the answer was "yes" or "no".
