FILE - In this Nov. 25, 2012 file photo, the leader of the center-right Catalonian Nationalist Coalition (CiU), Artur Mas waves to the crowd in front of a Catalonian flag being waved following regional elections in Barcelona, Spain. Mas has set Nov. 9, 2014 as the date for a planned referendum on possible independence, setting the stage for more confrontation with the central administration. Spain's Constitution says only the central government can call such a referendum and Prime Minister Mariano Rajoy recently rejected a request by Mas to approve one. Both the European Union and NATO have warned Catalonia it would be excluded if it seceded. (AP Photo/Manu Fernandez, File)
