Catalan, Scottish and Flemish organizations under the umbrella of the International Commission of European Citizens (ICEC) are calling for a demonstration in Brussels to demand the "universal right to the self-determination" to European institutions. The march will take place on March 30. Its core idea: self-determination is a democratic right of EU citizens and peoples, and the EU has a moral obligation to accept it. ICEC believes that the EU should "explicitly frame" this right.

ICEC spokeswoman Anna Arqué yesterday said  that the right to self-determination can not be limited by the "undemocratic opposition" of certain member states of the EU. These words by Arqué were pronounced the same day that the Spanish President Mariano Rajoy forecasted that Scotland would be automatically outside the EU if "yes" vote wins in next year's independence referendum. Several Catalan media have interpreted these words as a warning to the Catalan sovereignty movement.

On the Catalan side, Republican Left of Catalonia party (ERC, Catalan acronym) and civil society organization CIEMEN yesterday expressed their support for the 30th March demonstration. In Flanders and Scotland, the initiative is respectively supported by the Flemish People's Movement (VVB, Dutch acronym)  and the Scottish Independence Convention, a member of official "yes" campaign Yes Scotland.
