As Spain's Senate approved unprecedented proposals to take control of Catalonia under Article 155 of the Spanish constitution, EU President Donald Tusk said that for them, "nothing changes".

Catalonia's declaration of independence sought “open negotiation with the Spanish state” without pre-conditions, and urged the international community and European Union officials to “stop the ongoing civil and political rights violations and to follow up on the negotiating process” with Spain.

But EU President Donald Tusk retorted that “for the EU nothing changes”.

In a tweet, he said: “Spain remains our only interlocutor. I hope the Spanish government favours force of argument, not argument of force.”

Tusk’s remarks came amid a welter of criticism on social media, with user Colin Dunn suggesting that Catalonia had made a democratic choice, and adding: “EU should, and must, recognise that, or politically it risks irrelevance.”

Other users said Catalonia had been left with no choice, and James Utterson summed up the feelings of many: “The EU is a disgrace. Sitting on its hands whilst a member country prepares to violently attack its own people.”
