Spanish El Pais is reporting this. According to the newspaper, EU countries are open to sanctions to Venezuela if Maduro goes ahead with its constitutional assembly. 27 of the 28 member states approve this measure, except Portugal, who according to sources, is against any sanctions.
No Portuguese newspaper is reporting this right now, but i wouldn't be surprised if this dominated headlines tomorrow. Nonetheless, really bad decision by the Portuguese government.
Would that be because of pressure from BE and CDU?
