With the rise of the Covid Delta variant, Europe is divided on how to police its borders. Paris and Berlin are concerned about the influx of British tourists to southern Europe and are calling for a coordinated effort as the variant continues its inexorable advance across the continent. Its rise is rekindling tensions over the management of the EU's external borders. These divisions were much discussed at the beginning of the pandemic and resurfaced at the European summit in Brussels last week. Some want to err on the side of prudence; others such as Spain, Portugal and Greece are anxious to protect their all-important tourist seasons. There is no blanket health policy covering Europe, but there are health policies that need to be coordinated between the 27 member states.
