If Puigdemont does declare independence, Rajoy could invoke article 155 of the Spanish constitution, says The Times. This allows the government to take control of an autonomous region that acts contrary to “the general interest of Spain”. It has never been used before, and “would inflame the crisis further”.
Puigdemont has called on Brussels to mediate, says The Guardian. So far, the EU has been “nowhere to be seen”. On Monday, it issued a short statement calling the vote illegal and decrying the violence. But if the crisis escalates, the EU may be forced to intervene.
