The constitutional challenges that the Brexit negotiations have created in the United Kingdom: An overview

The Brexit negotiations raise a myriad of challenges for the constitutional system of the United Kingdom. This study focuses its attention on those that have appeared in the first phase: the constitutionality of the UK’s notice of withdrawal (under art. 50 TEU) and how it has affected the relationship between parliamentary sovereignty and the exercise of prerogative powers; the contents of the EU Withdrawal Bill and its possible extension of government law-making without parliamentary scrutiny as well as its implications for the devolved governments; and, lastly, the sensitive issue of the border of Northern Ireland with the South.
