The Process of Brexit: What Comes Next?

Front cover of 'The Process of Brexit: What Comes Next?'

After the UK voted to leave the EU in 2016, many questions were raised concerning the Brexit process: how would the terms of Brexit will be negotiated and agreed, and what roles will be played by the key actors: the executive, legislature, judiciary, devolved administrations, and general public in the UK, and the various parts of the EU?

Published in 2017, this report, written by Constitution Unit Deputy Director Professor Alan Renwick and published jointly by the Constitution Unit and the UCL European Institute, set out how the process of Brexit might unfold.  It begins by providing an overview of the negotiations, including what form any deal might have taken, whether the time available for reaching a deal could have been extended, and whether the UK could, if it wanted to, revoke the triggering of Article 50.  It then examines the possible roles and behaviours of each of the key actors in turn.  It argues that it would have been very difficult for the government to deliver the ambitious package set out by Theresa May in her Lancaster House speech on 17 January 2017 within the two-year timeframe that she envisaged. The report identified several possible other ways in which the Brexit process might have resolved itself.
