The exchange highlighted a debate that has refused to disappear from British politics: whether Brexit should be regarded as a settled decision or whether the UK should eventually seek a much closer relationship with the European Union.
For supporters of rejoining, the argument is increasingly centred on the economic consequences of Brexit.
They point to additional trade barriers, customs paperwork and the difficulties faced by businesses selling goods and services across the Channel. They argue that Britain’s departure from the single market and customs union created unnecessary friction with the UK’s largest nearby trading bloc.
That argument has gained renewed attention as economic growth remains weak and businesses continue to complain about the cost of regulation and international trade.
But Andrew Neil’s intervention offered a fundamentally different interpretation.
Rather than simply defending Brexit, he challenged the assumption that rejoining the EU would automatically return Britain to the political and economic circumstances that existed before the 2016 referendum.
That distinction is becoming increasingly important.
Even if Britain were eventually to seek membership again, the European Union of the future would not necessarily resemble the organisation Britain left.
The political landscape across Europe has changed dramatically.
Right-wing and populist parties have gained significant support in several major European countries, while mainstream parties have struggled to maintain the dominance they enjoyed a decade ago.
This means that the political calculation behind rejoining the EU cannot simply be based on nostalgia for the pre-Brexit period.
Britain would be joining a changing political project rather than returning to an unchanged institution.
That does not mean Neil’s economic argument settles the debate.
Britain’s growth performance relative to individual European economies can be influenced by numerous factors, including population growth, productivity, energy prices, investment, interest rates and differences in the structure of national economies.
Comparing the UK with Germany, France and Italy therefore requires considerable caution.
Germany, in particular, has faced major structural difficulties in recent years, including high energy costs, weak industrial demand and challenges facing its manufacturing sector.
France and Italy have their own long-standing economic problems.
Supporters of closer EU integration would argue that Britain should not judge its relationship with Europe simply by comparing headline GDP growth rates.
They would point instead to the potential benefits of reducing barriers to trade.
For many British businesses, the European market remains enormously important.
Small and medium-sized companies can be particularly sensitive to customs procedures, certification requirements and additional administrative costs.
A large multinational corporation may be able to absorb those costs relatively easily.
A small manufacturer employing a handful of people may not have the same resources.
This is one of the strongest arguments made by those who want Britain to rebuild closer economic ties with Brussels.
The debate is therefore not simply about whether Brexit “worked” or “failed”.
It is about what relationship Britain should have with the EU in the years ahead.
There are several possible positions between complete separation and full membership.
Britain could seek additional agreements covering trade, defence, research, energy, migration or professional qualifications without formally rejoining the bloc.
Such an approach could appeal to voters who believe Brexit should remain in place but who also want fewer practical barriers between Britain and its European neighbours.
That middle ground may become increasingly important.
The Liberal Democrats have long advocated closer relations with Europe, while some Labour politicians have also expressed support for reducing Brexit-related trade friction.
However, a formal attempt to rejoin the EU would almost certainly provoke a much larger political confrontation.
It would raise difficult questions about the single market, customs union, freedom of movement and the UK’s willingness to accept common European rules.
It could also reopen one of the most divisive political arguments of the past decade.
For Brexit supporters, the prospect of rejoining would represent a reversal of a democratic decision made in the 2016 referendum.
For pro-European voters, however, the passage of time could make a future referendum or membership application a legitimate democratic question.
The generational dimension could also become increasingly important.
Millions of younger Britons who were too young to vote in 2016, or who were not born at the time, may have very different views about Britain’s relationship with Europe.
At the same time, many older voters who strongly supported Brexit remain determined to protect the decision.
The political divide therefore has the potential to evolve rather than simply disappear.
Andrew Neil’s intervention also highlighted another weakness in the argument for automatically returning to the EU.
Britain cannot assume that European membership would solve its domestic economic problems.
The EU itself faces significant economic challenges.
Germany’s industrial difficulties, France’s fiscal pressures and Italy’s persistent debt burden demonstrate that membership of the bloc does not guarantee rapid growth.
The European Union is also dealing with major strategic challenges, including the war in Ukraine, energy security, competition with China and an increasingly unpredictable relationship with the United States.
Any future British government considering membership would therefore have to decide whether the benefits of integration outweighed the obligations involved.
That is a far more complicated calculation than simply asking whether Brexit made Britain richer or poorer.
There is also the question of sovereignty.
One of the central arguments made by Brexit supporters was that Britain should have greater control over its laws, borders and economic policy.
Rejoining the EU would inevitably involve accepting a significant degree of shared rule.
Supporters of membership would argue that this is precisely what makes the European project effective.
Critics would say it would recreate some of the constraints that Brexit was intended to remove.
That disagreement is unlikely to disappear.
Meanwhile, the political developments Neil highlighted across Europe could make Britain’s future relationship with the EU even more complicated.
If nationalist and right-wing parties continue gaining ground, the character of the European Union could change significantly over the next decade.
That raises a fascinating possibility.
Britain could eventually seek closer ties with an EU that is itself more nationalist, more restrictive on migration and more sceptical of the policies associated with the European political centre of the 2010s.
The political arguments of 2016 might therefore look very different by the time any future government seriously considers membership.
For now, however, the immediate political priority for Britain is likely to be improving the relationship without reopening the entire Brexit settlement.
Businesses want predictable rules.
Consumers want competitive prices.
Security officials want greater cooperation with European partners.
Universities want research links.
Young people want opportunities to study and work abroad.
At the same time, Brexit supporters want the UK to retain the sovereignty they believe was restored by leaving the EU.
Finding a compromise between those competing objectives could be much easier politically than attempting to reverse Brexit entirely.
The Question Time debate nevertheless demonstrates that the issue remains politically alive.
Calls to rejoin the EU are no longer confined to a small group of activists or politicians who opposed Brexit from the beginning.
They are increasingly part of a wider argument about Britain’s economic future.
But Neil’s warning is equally significant.
Britain cannot simply look backwards.
The Europe of 2026 is not the Europe of 2016, and the Europe of 2030 or 2035 could look even more different.
Any serious discussion about Britain’s future relationship with the continent therefore needs to begin with the Europe that actually exists — not the Europe remembered from before the referendum.
For now, the debate appears far from settled.
Pro-Europeans will continue to argue that closer integration could remove unnecessary barriers and improve Britain’s economic prospects.
Brexit supporters will insist that the country should use its independence to pursue a different economic and political strategy.
And in the middle will be millions of voters who may not want either extreme.
The question facing Britain’s political class is therefore not simply whether Brexit was right or wrong.
It is whether Britain can build a successful relationship with Europe without repeating the divisions that produced Brexit in the first place.
