A Changed World Demands a Changed Conversation About Brexit
A decade has passed since the United Kingdom voted to leave the European Union, and the consequences of that decision are no longer a matter of speculation. They are embedded in trade figures, investment data, and the lived economic reality of millions of British households. Against this backdrop, Liberal Democrat leader Sir Ed Davey has done something that most mainstream politicians have been reluctant to do: he has called openly and ambitiously for deeper reintegration with Europe. And he is right to do so.
For years, revisiting the Brexit settlement was treated as a political third rail — too toxic to touch, too divisive to debate. That era appears to be ending. The mood in Britain is finally shifting, and understanding why requires an honest look at what Brexit promised, what it delivered, and what a more pragmatic relationship with the EU could offer in its place.
What Brexit Actually Promised — And What It Delivered
The 2016 Leave campaign was built on a powerful but deeply misleading proposition: that Britain could sever its ties with its largest trading partner at little or no cost. Freed from the regulatory constraints of Brussels, the argument went, the UK would flourish as a nimble, globally connected economy. A bonfire of red tape, new trade deals across the world, and full control over borders would more than compensate for any disruption to European commerce.
None of that held up to scrutiny. Trade with the EU became more complex, more expensive, and more bureaucratic almost immediately after the UK's exit from the single market and customs union. Small and medium-sized businesses that relied on frictionless European trade faced a wall of new paperwork. Exporters in sectors from food to financial services encountered barriers that did not exist before. The promised trade deals with countries like the United States proved elusive or underwhelming in their economic impact.
Meanwhile, the economic cost of rupture — widely forecast by economists before the vote — was steadily vindicated. Study after study has pointed to a significant and persistent drag on UK growth attributable to Brexit. The Office for Budget Responsibility and independent economic institutions have consistently identified the departure from the single market as a structural headwind. In the language of economics, this is not a short-term adjustment but a long-term reduction in the country's productive potential.
Why Immigration Derailed the Remain Argument
If the economic case for remaining in the EU was strong, why did it fail to win the argument in 2016? The answer lies largely in immigration — specifically, in the principle of free movement that underpins membership of the European single market.
For many Leave voters, the ability to control who enters the country was not just a policy preference; it was a matter of sovereignty and cultural identity. The Remain campaign struggled to respond effectively, because the honest answer — that meaningful access to the single market requires accepting free movement of people — was politically uncomfortable for a Labour Party anxious about its traditional working-class base and a Conservative Party already battered by years of internal division over Europe.
This discomfort imposed a kind of taboo on the subject that persisted long after the vote. Even as evidence of economic damage mounted, mainstream politicians from both major parties avoided any serious discussion of reintegration, fearing that it would be read as a betrayal of the referendum result or an invitation to relitigate a settled question.
Ed Davey's Case: Economic and Strategic Reality
What makes Sir Ed Davey's position significant is not simply that he has broken this taboo, but that he has done so by anchoring the argument in present-day economic and strategic reality rather than nostalgia for pre-Brexit arrangements.
The world of 2026 is not the world of 2016. Geopolitical pressures — from the war in Ukraine to shifting alliances in the Indo-Pacific — have underscored the value of deep cooperation between democratic allies. Energy security, defence spending, climate policy, and supply chain resilience are all areas where the UK and EU have overlapping interests that are better served by collaboration than by managed distance. The strategic case for closer ties has grown substantially stronger.
On the economic side, a return to closer alignment with European markets — whether through rejoining the single market, negotiating improved customs arrangements, or pursuing sector-by-sector agreements — could meaningfully reverse some of the growth lost over the past decade. The precise form of any reintegration matters enormously, and the political trade-offs around free movement remain real. But the conversation needs to happen, and Davey is right to insist that it does.
What Closer UK-EU Ties Could Look Like in Practice
Rejoining the EU outright is not a near-term political reality, and few serious analysts advocate for it in the immediate term. But there is a wide spectrum of options between the current arrangements and full membership, and the UK has barely begun to explore them.
- Single market alignment: Rejoining the European Economic Area, as Norway and Iceland have, would restore frictionless access to EU markets in exchange for accepting single market rules and contributions to EU programmes.
- Customs union membership: A customs union arrangement, similar to Turkey's relationship with the EU, would eliminate tariffs and simplify trade in goods without requiring full regulatory alignment.
- Sectoral agreements: Targeted deals in areas like financial services, professional qualifications, or agricultural standards could reduce specific barriers without a comprehensive framework.
- Youth mobility schemes: A bilateral agreement allowing young Britons and Europeans to live and work across borders could restore some of the social and economic dynamism that free movement provided.
Each of these options involves trade-offs, and none of them is cost-free. But the current baseline — an arms-length relationship that imposes ongoing economic friction — is itself not cost-free. The question is not whether to pay a price, but which arrangement offers the best value for Britain's long-term prosperity and security.
The Political Moment Has Finally Arrived
After years of enforced silence, the political conditions for a serious debate about Britain's relationship with Europe are finally emerging. Public attitudes have shifted. Younger voters who were not part of the 2016 decision are now a growing electoral force, and polling consistently shows greater appetite for closer EU ties among the broader population. The economic evidence is no longer deniable, and the strategic argument has been sharpened by global events.
Ed Davey's call for more ambitious reintegration brings necessary honesty to a debate that has been constrained for too long by political caution. A changed world does change the argument. Britain deserves a grown-up conversation about what its relationship with Europe should look like — and that conversation is long overdue.
