The Sunday Debate: We Were Right To Brexit

It was always going to be a disaster. Queues of HGVs stretching miles from Dover. The Good Friday Agreement threatened by the controversial Northern Ireland Protocol and increased support for Scottish Independence. That’s the argument of the doomsayers in this debate.

Episode Summary

Executive Summary: Intelligence Squared hosted a Brexit debate weighing whether the UK was right to leave the EU. Daniel Hannan and Robert Tombs argued Brexit avoided predicted catastrophe, restored control, and opened global opportunities; Dominic Grieve and Stella Creasy argued it inflicted economic damage, reduced influence, and delivered few promised benefits. The audience initially leaned against the motion and remained so after the debate.

Main Topics: Economic performance after Brexit (Priority: 5/5): Speakers disputed whether Brexit harmed or helped growth, trade, investment, inflation, and jobs, with Remain side citing lasting GDP and export losses while Leave side argued forecasts of collapse never materialized. Sovereignty, democracy, and control (Priority: 5/5): Hannan and Tombs framed Brexit as a democratic assertion of self-government against an undemocratic EU, while Grieve and Creasy argued sovereignty is constrained by practical dependence and that Brexit weakened Britain’s capacity to act effectively. Foreign policy, Ukraine, and global influence (Priority: 4/5): The panel debated whether Brexit improved or diminished Britain’s ability to shape events abroad, especially in response to Ukraine and relations with allies and the EU. Immigration and border control (Priority: 4/5): Leavers said Brexit fulfilled a demand for controlled, legal immigration; opponents said immigration remained high and the system became more cumbersome through visas and labor shortages. Trade deals and international orientation (Priority: 4/5): Hannan and Tombs emphasized new or expanded trade agreements and a pivot beyond Europe, while Creasy and Grieve said most deals were rolled over or low-value and the EU remained the dominant commercial partner. Northern Ireland and the protocol (Priority: 3/5): All sides referenced the Northern Ireland Protocol as evidence of Brexit’s difficulty, with Leavers blaming EU rigidity and the Benn Act, and Remainers seeing it as proof of the costs of leaving. Political consequences and public trust (Priority: 3/5): Speakers linked Brexit to polarization, dishonest politics, and the rise of Boris Johnson, while also arguing about whether Brexit had become a convenient scapegoat for wider UK failures.

Key Arguments: Daniel Hannan argued that the worst predictions about Brexit—market collapse, unemployment spikes, mass recession, and border chaos—did not happen, so the vote was not catastrophic. Hannan also claimed the UK gained freedom to pursue trade agreements, support Ukraine decisively, and run a faster vaccine rollout outside EU constraints. Dominic Grieve contended Brexit was the largest modern self-inflicted wound, citing GDP loss, export declines, financial-sector relocation, and reduced diplomatic influence. Grieve argued the UK’s post-Brexit problems stem from choosing cooperation away from nearest neighbors, not from EU overreach. Robert Tombs said Brexit was fundamentally about democracy and rejecting an undemocratic, elite-run EU that Europe itself increasingly distrusts. Tombs maintained Britain’s long-term economic future lies beyond Europe and that trade with the rest of the world is growing faster than trade with the EU. Stella Creasy argued the UK has taken the costs of leaving without the promised freedoms, calling it “Brexit in name only.” Creasy highlighted higher trade barriers, supply-chain friction, reduced consumer protections, and little meaningful regulatory divergence as evidence that Brexit has underdelivered. The speakers against the motion said Britain must now fix the consequences of Brexit rather than re-litigate it, while the speakers for the motion said the real issue is whether the EU was ever willing to respect British self-government.

Pivotal Quotes: "we were right to Brexit" — Connor Boyle / motion title: Introduced as the central motion for debate "the biggest mistake in modern British history" — Dominic Grieve: Opening attack on Brexit’s economic and constitutional effects "Brexit was a rejection of pessimism and declinism" — Robert Tombs: Closing case for the motion, framing Leave as democratic confidence "we have had Brexit in name only" — Stella Creasy: Creasy’s core argument that promised freedoms were not delivered

Implications: The debate shows Brexit remains politically and economically contested, with little consensus on benefits. For business and policymakers, the focus is now on managing friction, regulation, and trade realities rather than revisiting the referendum itself.
