The European Union says it has completed preparations for the potentially-chaotic scenario in which Britain leaves the bloc without a Brexit deal, but talks on how to manage the Irish border are continuing.

Amid doubt about whether Britain will endorse the divorce agreement by Friday, the EU says a no-deal Brexit on the new departure date, April 12, “is increasingly likely.”

The European Commission said Monday that “this will obviously cause significant disruption for citizens and businesses,” and noted that Britain will leave “without any transitionary arrangements.”

The commission says it has published 90 preparedness notices for citizens and businesses and made 19 proposals for new legislation.

The remaining 27 EU countries are hiring hundreds of staff to conduct extra border and customs checks.
