Tsunami Democratic have called for a rally to be held outside the Camp Nou on December 18, just hours before Real Madrid take on Barcelona in the season's first Clasico.

A statement was released on Tuesday that explained over 18,000 people have registered to take part in the protest, which will get underway at 16:00, just four hours before kick off.

Four focal points have been chosen around the stadium, depending on the geographical origin of the protesters.

Additionally, they have ensured that those registered to participate have received "the relevant slogans" and are ready for "a day that will be followed by 650 million people worldwide".

The group have justified the plans as "Catalonia is going through an exceptional situation and it's necessary to act exceptionally".

"At the moment," they explained, "an important part of the Catalan population suffer exclusion for reasons of ideology.

"They cannot exercise fundamental rights without repression.

"Dozens of people are or have been in prison simply for exercising and promoting these rights."
