‘All non-essential travel should be strongly discouraged both within the country and of course across borders,’ Ursula von der Leyen, head of the European Commission, has said. As a result of the Covid crisis, the dream of open borders across the continent of Europe has never seemed so imperilled. Meanwhile, a post-Brexit Britain has the ability to flex its borders as much as it chooses. To some Brexiteers, this alone makes Brexit worth it.
The Schengen agreement was signed in 1985 and became pan-EU in 1999, meaning that, from then on, any country without an opt-out needed to allow free movement of people from any other signatory country (almost all of the rest of the European Union). The United Kingdom and Ireland were amongst the few countries within the EU to opt out, meaning that, while freedom of movement still applied in those countries, it was tempered by the ability to carry out passport checks.
