The parliamentary battle over Brexit and the constitution

Today sees the publication of a new book by the Unit’s Meg Russell and Lisa James, The Parliamentary Battle over Brexit. Here the authors summarise some of its key findings about why parliament was drawn into such controversy over the implementation of Brexit. They reflect on what these events teach us about our constitution, as well as what may need to change in order to avoid repeating such problems, and to mend the damage done.

The UK’s arguments over what became known as Brexit began long before the June 2016 referendum, and continued with increasing bitterness afterwards. Parliament was often central, both as a venue for such arguments, and in terms of disputes about its proper role. It and its members frequently faced criticism and blame. Our new book, published today, charts The Parliamentary Battle over Brexit, from the early pressures for a referendum, through disputes about the triggering of Article 50 and control of the House of Commons agenda, the repeated defeats of Theresa May’s deal, and Boris Johnson’s unlawful parliamentary prorogation, to the UK’s eventual departure from the EU following his deal. The book charts what happened, but also asks what went wrong and whether things could have been handled differently. It reflects on what these events teach us about the functioning of our constitution, and what if anything might need to change.

The book includes a wealth of detail about key political moments, and the roles of different individuals and groups. Here we focus on some of the bigger questions about the lasting legacy of the battles over Brexit for the culture and institutions of UK politics, and particularly for the place of parliament itself. A fuller version of this analysis appears in the final chapter of the book.

Referendums and public participation

The referendum of 23 June 2016 was only the third ever such UK-wide vote (the first being on European Community membership in 1975, and the second in 2011 on changing the House of Commons voting system). The handling of the referendum was the single biggest error of the Brexit process, from which many other difficulties flowed.

Unlike the 2011 referendum, which was underpinned by legislation setting out the detail of the proposed new voting system, no clear prospectus was offered to the voters for Brexit. Prime Minister David Cameron hoped to use the vote – described disapprovingly by the House of Commons Public Administration and Constitutional Affairs Committee as a ‘bluff call’ referendum – to make the question of Brexit go away. Parliament never debated the substance of the question, the government did not detail the options, and civil servants were forbidden from preparing for a Leave vote. Leave campaigners argued at the level of principle, rather than on a specific plan. As one Brexit-supporting interviewee told us, ‘it was only [after the referendum] that different types of Brexit started coming to the fore. Soft Brexit and hard Brexit had never been canvassed before the referendum; the expressions were coined afterwards’. Issues that would soon come to dominate the agenda, such as membership of the Customs Union or Single Market, and crucially the Northern Ireland border, were barely mentioned during the campaign. This left the government – and parliament – in a very difficult position. The different options for Brexit had to be established only after the vote had taken place, and on this the voters had conveyed no clear instruction.

Why Labour should adopt a two-stage approach to House of Lords reform

Today the Constitution Unit publishes a report jointly with the Institute for Government and Bennett Institute on the options for House of Lords reform. Here, in the second of two posts summarising its conclusions, report author Meg Russell argues that if Labour wins the next election, it should pursue a two-stage approach. This would begin with immediate urgent changes to the appointments process and hereditary peers, while the party consulted on larger-scale proposals such as those set out in the Brown report.

Today the Constitution Unit publishes a new report, House of Lords reform: navigating the obstacles, jointly with the Institute for Government and the Bennett Institute at the University of Cambridge. This is the second of two posts summarising some of the report’s conclusions, with a particular focus on Labour’s options for Lords reform.

The previous post explored proposals from Labour’s commission chaired by former Prime Minister Gordon Brown, for an elected ‘Assembly of the Nations and Regions’. It suggested, on the basis of past UK and international experience, that large-scale reform of this kind will be difficult to achieve, and could not be actioned by Labour immediately. The Brown report leaves many open questions on which careful consultation and deliberation would be required. Meanwhile, there are clear problems with the House of Lords which are widely recognised, and would be relatively straightforward to deal with. This post focuses on such beneficial small-scale changes, including:

  • placing a limit on the size of the House of Lords
  • agreeing a formula for the sharing of seats
  • introducing greater quality control on appointments
  • removing the remaining hereditary peers.

More detailed consideration was given to the first three of these options in another recent post on this blog. Hence this one deals with them quite briefly, then draws the strands together, considering a possible strategy for the Labour Party on Lords reform if it comes to power.

Placing a limit on the size of the House of Lords

One of the most visible difficulties with the House of Lords is its growing size. Reform by Tony Blair’s government in 1999 removed most hereditary peers, slashing the chamber from more than 1,200 members to 666. But since then, its size has crept gradually upwards again. There was a net growth of around 70 members under Blair, and well over 100 under David Cameron – though Gordon Brown and Theresa May each presided over net reductions of around 30 members. Boris Johnson’s appointments were also excessive, and concern remains about his possible resignation honours list. Currently, the size of the House of Lords hovers around 800.

The misleading of parliament greatly troubles the public: something should be done

The recent case of Boris Johnson, now referred to the Committee of Privileges, highlighted perceived problems in handling allegations of MPs misleading the House of Commons. Meanwhile, Constitution Unit research shows that the public want tough sanctions for such behaviour. Meg Russell summarises these findings, in the context of the Johnson inquiry, and a parallel inquiry by the Commons Procedure Committee on correcting the record – arguing that serious consideration should be given to tightening the rules.

Recent context

Concerns about the truthfulness of politicians are nothing new. Indeed, historically politicians may often have been subject to unfair criticism in this area. Within parliament, and particularly with respect to ministers, there is a strong expectation that members should tell the truth. The December 2022 edition of the Ministerial Code states in its very first article (as did its predecessors) that:

It is of paramount importance that Ministers give accurate and truthful information to Parliament, correcting any inadvertent error at the earliest opportunity. Ministers who knowingly mislead Parliament will be expected to offer their resignation to the Prime Minister.

Within parliament, this matter is in theory handled equally seriously. Erskine May states that ‘The Commons may treat the making of a deliberately misleading statement as a contempt’. As such, this behaviour may be referred to the Committee of Privileges for investigation leading to possible punishment.

These matters reached prominence under the premiership of Boris Johnson, who was frequently accused – by MPs and others – of misleading parliament. Things came to a head over statements that he had made about ‘partygate’ (the holding of social gatherings in 10 Downing Street during the COVID-19 lockdowns), which ultimately resulted in Johnson being referred to the Committee of Privileges. It is currently undertaking an investigation. Aside from the allegations themselves, controversy has reached the news over Johnson submitting a legal opinion to the committee questioning its processes, and over his legal advice being funded by the public purse. Hearings by the committee are expected in due course, with a report later this year.

Meanwhile, the House of Commons Procedure Committee is conducting a parallel inquiry which also addresses handling of misleading statements to parliament, with a focus on ‘correcting the record’. Unlike the Committee of Privileges, the Procedure Committee has invited evidence on general issues, rather than a single case, and it exists to propose changes to Commons procedures. Understandably, therefore, it has attracted evidence from those concerned about recent events.

Why Rishi Sunak should take the initiative on standards reform

Rishi Sunak has appointed a new Independent Adviser on Ministers’ Interests, but there is still a need for the role to be strengthened to ensure the new Adviser has genuine independence and freedom to act. Concerns have also been raised about the standard of recent appointments to the House of Lords. Peter Riddell argues that Sunak should follow the example of John Major and take the initiative on standards reform.

Rishi Sunak has so far been stronger on aspirations to improve standards in public life than on his actions, which have largely continued the approach of his predecessors. Ministers have reaffirmed limits to the role of independent regulators and scrutiny by reasserting executive prerogatives.

On the positive side, in his first comments on entering 10 Downing Street, Sunak promised that his government would have ‘integrity, professionalism and accountability at every level’. Trust, he said, is earned. And in his personal foreword to the Ministerial Code issued just before Christmas, he referred to upholding the Principles of Public Life (commonly known as the Nolan principles), which Boris Johnson had omitted from the May 2022 version. At the same time, Sunak appointed Laurie Magnus as the new Independent Adviser on Ministers’ Interests, six months after the resignation of predecessor Lord (Christopher) Geidt.

The role of the Independent Adviser

The remit of the Adviser has not, however, been strengthened since the compromise changes of last May, which attracted criticism at the time. The government adopted some of the package proposed by the Committee on Standards in Public Life (CSPL) in its Upholding Standards in Public Life report of November 2021, which recommended a graduated system of sanctions solely in the hands of the Prime Minister, combined with greater independence for the Adviser in launching inquiries and determining breaches of the Code. As Lord (Jonathan) Evans of Weardale, the committee’s chair, commented in June 2022, the government accepted the former but not the latter in the form proposed.

The Adviser will now be able initiate their own investigations but only after ‘having consulted the Prime Minister and obtained his consent’. The requirement for prime ministerial consent is justified on the grounds that the Prime Minister is constitutionally responsible for appointing and dismissing ministers. As Boris Johnson said in a letter to Lord Evans in April 2021, this meant that, ‘I cannot and would not wish to abrogate the ultimate responsibility for deciding on an investigation into allegations concerning ministerial misconduct’. Moreover, the Prime Minister will also continue to have the right to decide when any report by the Adviser is published – risking lengthy delays, as has happened in the past – and on the significance of any breach of the Code, as well as on the form of any sanctions. Parliament is still left with no role in approving the Code or its implementation.

The Constitution Unit blog in 2022: a guide to the last 12 months of constitutional news

The four years preceding 2022 were a fascinating time to be writing about the UK constitution, its institutions and those involved in working within them. It had got to a point where it didn’t seem life could get any more interesting. And then 2022 gave us two prime ministerial resignations and an end to the longest monarchical reign in British history. As the year comes to an end, blog editor Dave Busfield-Birch offers a roundup of the 12 months just gone, as well as a look at the reach of the blog through the lens of its readership statistics. 

2022 included a seven-week period in which we transitioned from one monarch to another and had three Prime Ministers. Two of those Prime Ministers – Boris Johnson and Rishi Sunak – were fined for breaking COVID-19 lockdown regulations earlier this year and the third, Liz Truss, now has the dubious distinction of being the Prime Minister to have held office for the shortest time in modern history. In addition, we lost the longest-reigning monarch in British history and welcomed the first monarch to have the benefit of a seven-decade apprenticeship and a new Prince and Princess of Wales. The state of the Union also appears less stable, with Scotland found to be unable to legislate for an independence referendum and May’s elections in Northern Ireland leading to political deadlock that has no immediate end in sight. Below are our most popular blogs from the past year, preceded by a personal selection by me, at the end of my fifth year as blog editor.
