In mid-January 2019 the UK Parliament rejected the proposed European Union (EU)-UK agreement that provided for a more or less orderly Brexit. Two months ahead of the deadline, the British government is expected to further push for an approval of the agreement, but a disorderly separation may now be the most likely scenario.
Accordingly, EU nations are getting ready to minimize expected disruptions. The European Commission, in December 2019, published its own contingency plans  identifying 14 key policy areas  for EU member states to adopt. Nevertheless, many areas remain under the responsibility of EU members and their states of preparation, as well as their key areas of concern, vary.
Here is what is known as of mid-January 2019
The Austrian government has prepared an omnibus law in case of a hard Brexit which focuses on issues of citizenship as an acquired dual citizenship is normally not allowed under Austrian law.
