The Spanish Foreign Affairs Minister, José Manuel García-Margallo, stated that a unilateral declaration of independence would condemn Catalonia "to roam across space" and that it would be "excluded from the European Union for the centuries of the centuries". García-Margallo, who is one of the most vocal members of the Spanish Executive against Catalonia's independence, stated that such a scenario is "a high risk operation". He criticised the politicians supporting independence, who "put at risk a population that is essentially European", which goes against the will of a majority of Catalans "who want to be part of the European area". "Secession is extremely harmful for Spain but particularly harmful for Catalonia", he insisted. On the same day, the Candidate of the Greens to chair the European Commission, German Ska Keller, stated she was supporting Catalonia's right to self-determination.
