Protest group Tsunami Democràtic have sent out a communication calling on as many people as possible to come to the Catalan capital on the day of the clásico football match between Barcelona and Real Madrid.

The game will be played on Wednesday, December 18 at 8 pm, after being rescheduled from October 26 for security reasons. A huge pro-independence protest was already due to take place in Barcelona, drawing hundreds of thousands of people.

Tsunami Democràtic are also urging protesters who have tickets to the match to communicate that internally with protest organizers through channels on their application.

The group said they were aware of how much such a huge football match as the clásico “transcends” the sport, while describing the “political moment” the country finds itself in as “exceptional.”

“Tsunami Democràtic are launching a new date for mobilization on December 18 inviting everybody to save the date and come to the city of Barcelona.” They are also activating a functionality on their application for subscribers to confirm their attendance.

“With prisoners, people in exile, no self-determination, nor a spate of fundamental rights, there is no normality. On the 18th, we’re all playing the clásico. This is the force of the people,” their statement concludes.

The Tsunami Democràtic group of protesters were behind the shut down of Barcelona airport on the day Spain’s Supreme Court released the verdict to the Catalan Trial, jailing nine pro-independence leaders to lengthy prison terms of between 9-13 years.

They also organized the occupation of the AP-7 motorway on and near the border with France for two days after the November 10 general election.
