It is widely believed that Brexit has been thoroughly bad for the United Kingdom’s internal unity and coherence.
First, Scotland’s move for independence, and hopefully trying to join the European Union, (possibly with complete separation from its bigger English neighbor), has been strongly reinforced — despite bitter current internal struggles inside the ruling Scottish Nationalist Party. Elections to the Scottish Parliament in May could give the breakaway movement a majority and bring the issue of a new Scottish referendum on independence to a head.
Second, Northern Ireland’s anomalous post-Brexit position, both within the EU single market and yet also within the now-separate U.K. internal market, is rousing growing tensions and re-awakening debate about the province’s future status, which could even lead, as so often in the past, to violence.
