A further referendum on Brexit is central to many parties’ general election pledges. Today, the Constitution Unit launches a new report examining how such a vote might come about and what form it might take. This updates previous work conducted last year. In this post, adapted from the report’s final chapter, Alan Renwick, Meg Russell, Lisa James and Jess Sargeant sum up the key conclusions. They find that, though it would not be without difficulties, a vote on Johnson’s deal may be the quickest option and the one most likely to command public legitimacy.
The Constitution Unit’s latest report, The Mechanics of a Further Referendum on Brexit Revisited: Questions for the New Parliament, is published today. It significantly updates our previous analysis of the mechanics of a further Brexit referendum, exploring the circumstances that might lead to a further referendum on Brexit, and the form that such a referendum might take. The report does not advocate for or against a referendum, or assess the broader impact that such a vote might have. Rather, it explores the practical implications of the different options: in terms of the processes to bring a referendum about, the standards that it should meet, the options for reforming regulation, and, crucially, the timetable.
The minimum timetable from the point at which parliament decides in principle to hold a referendum to the date on which that referendum is held is roughly 22 weeks – or five months. Claims that organising a referendum would take a year or more are therefore overstated. However, very clearly, a decision to proceed with a referendum would require a further extension to the Article 50 period, which currently expires on 31 January 2020. And there are various factors that could put pressure on the minimum timetable, requiring a somewhat longer period of planning and preparation. This post (adapted from the report’s final chapter) considers how the pieces fit together, and what the overall timetable would likely be. The most obvious implication of this is for the length of Article 50 extension which a future government should request if seeking to hold a referendum.
The report considers the factors which could impinge on the timetable in detail, but in brief they include the following:
- Is the referendum to be held on a pre-existing Brexit deal, or is time required (as Labour’s policy implies) for further renegotiation before proceeding to a referendum?
- How contentious would the referendum bill be in parliament? This depends partly on the constellation of parties and groups in the House of Commons after the general election, and also on the content of the bill.
- What form would the referendum question take? This may be one of the points of contention in parliament. We conclude that a three-option referendum is unlikely. Moving to such a format would slow down the process.
- To what extent would campaign regulation be tightened up and updated via the referendum bill? Some updating is essential, and could be incorporated within the 22-week timetable. Other more major changes might be desirable, but in the interests of speed would likely be set aside.
- Would the referendum result be made legally binding? This is not essential, but would be beneficial to provide clarity and certainty for voters. Preparing for a fully legally binding referendum would be likely to take slightly more time.
