"Reform or be destroyed," the German daily Der Tagesspiegel warns the European Union in the wake of the UK exit vote. Papers across Europe are calling for radical changes to counter the rise of populism sweeping the continent, warning that leaders such as Geert Wilders and Marine Le Pen are "great simplifiers" who threaten democracy by appealing to irrational fears. Spanish newspaper El Pais commented that "populism is tearing Europe apart," but warned that any changes to the EU should not be made in an effort to appease "anti-establishment" discourse.
