EU President apologizes for Catalan 'error'

Spanish EU Parliament member Enrique Calvet Chambon posted on Facebook on Monday that Schulz had written him a letter, acknowledging the error.

Calvet had written a complaint about official Parliament documents which included Catalonia alongside the 28 member states as if it were its own country.

Agendas distributed to representatives with the contact details of national parliaments in each country had also included information for the Catalan parliament, which Calvet said "seemed to grant this regional parliament with the status of a nation" and was unfair to other regions.

"This is a serious error with serious political consequences and unfortunate discrimination for other Spanish and European regions," Calvet wrote on Facebook.
