The Background: Britain being Great Britain, when history gets written and rewritten, there will be a thick fat chapter on Brexit – a sobriquet signifying an important, significant and above all a consequential development in world history. This piece is being written on 26th June 2026, the tenth anniversary of this all important event. Ten years after the United Kingdom formally left the European Union, Brexit remains one of the most contested political decisions of the 21st century. It was a rupture that promised sovereignty, control and renewal, yet delivered paradoxes of pride and pain in equal measure. As Britain marks this anniversary, this story is not only about trade deals and customs borders, but also about the political turbulences that saw Prime Ministers come and go with unusual speed and as routine events. The agonies and ecstasies of Brexit are inseparable from the fragility of leadership at 10 Downing Street where short stints became the norm in a decade defined by uncertainty. The original objectives of Brexit were deceptively simple – too simple, in fact. The Leave campaign distilled its message into the catchy slogan “Take Back Control.” Sovereignty was the lodestar. Britain would reclaim its laws from Brussels, free itself from the jurisdiction of the European Court of Justice and restore its own parliamentary supremacy. Immigration was another pillar. Free movement within the EU had brought millions of workers from Eastern Europe. While many contributed to the economy, anxieties about cultural change and pressure on public services fuelled demands for stricter borders not to speak of the fear of unchecked terrorist activities at every street corner. Economic freedom was the third promise. Advocates argued that Britain, unshackled from the EU bureaucracy, could strike independent trade deals, revive industries and chart its own global course. Beneath all these tangible goals, lay a symbolic one: Brexit was about national identity, a reassertion of British distinctiveness, a harking back to notions of empire and global reach. The referendum of 2016 revealed a fractured nation. England and Wales voted to leave, Scotland and Northern Ireland preferred to remain. London, cosmopolitan and globally connected, stood apart from rural England – a lonely symbol of a bygone era. Generational divides were stark – younger voters overwhelmingly supported to remain, while older voters wanted to leave. For Brussels, Brexit was both a shock and a warning. Fears of a contagion with other nations following Britain’s path – prompted the EU to adopt a firm stance. Protecting the integrity of the single market became paramount and the EU’s unity in negotiations was, ironically, strengthened by Britain’s departure. Global powers watched with mixed emotions. The United States under Donald Trump welcomed Brexit as a triumph of nationalism. China, for their own reasons, saw opportunities in Britain’s isolation even as India and other Commonwealth nations viewed Brexit as a chance to renegotiate ties though expectations often outpaced reality.
The Revolving Door: The flag bearers of Brexit shaped its trajectory in ways that revealed both the promise and the perils of populist politics. David Cameron, who called the referendum expecting Remain to win, resigned in defeat. Nigel Farage, the populist face of Leave, celebrated Brexit as a victory against elites, though his own role diminished afterwards. Theresa May, tasked with negotiating withdrawal, struggled with parliamentary deadlock, her premiership consumed by failed compromises. Boris Johnson, the flamboyant advocate of “Get Brexit Done,” managed to secure a decisive mandate in 2019, delivering a hard Brexit. Liz Truss, who followed Johnson, lasted just 45 days, undone by her own economic mismanagement. Rishi Sunak, by 2026, sought to stabilise post-Brexit Britain, balancing sovereignty with economic pragmatism. Their preferences – from Johnson’s hardline stance to May’s cautious compromise – defined the contours of Brexit. Ten years on, the promises of prosperity and control still remain contested and ever more elusive. Was Brexit the cause of this instability or did it merely exacerbate existing fragilities? The answer lies in nuance. Cameron and May’s exits were directly tied to Brexit. Johnson’s rise was built on Brexit, and his fall, while linked to scandals, was shaped by the exhaustion of Brexit politics. Brexit created permanent instability in the Conservative Party, splitting it into factions of hardliners and pragmatists. This made leadership fragile. The economic consequences of Brexit amplified public dissatisfaction, making leaders vulnerable. Yet later instability also had other causes. Truss’s downfall was fiscal mismanagement. Johnson’s scandals were personal and political. Sunak’s challenges stemmed from global crises. Brexit lit the fuse; politics and economics kept the fire burning.

The Consequences: Ten years on, the result of Brexit are visible across economics, politics, society and strategy. Economically, leaving the single market introduced customs checks, regulatory divergence, and barriers for exporters. Financial services, once the jewel of London, saw parts of their operations shift to Frankfurt, Paris, and Dublin. Studies suggest Britain’s economy grew more slowly than it would have inside the EU, with productivity lagging behind. The Northern Ireland Protocol, designed to avoid a hard border, created a de facto customs border in the Irish Sea, fuelling political tensions. Politically, Brexit reignited calls for Scottish independence with Scotland arguing that its Remain vote was simply ignored. On the other hand, far from unravelling, the EU emerged more united, wary of populist contagion. Britain sought to redefine itself as “Global Britain,” joining trade pacts like CPTPP, but its influence in Europe progressively diminished. Socially, Brexit curtailed free movement, but labour shortages in healthcare, agriculture and hospitality exposed the costs involved. Identity politics sharpened cultural divides with younger generations viewing Brexit as a betrayal of openness. Strategically, Britain remained a key NATO member, but its absence from EU defense initiatives clearly limited its influence. It sought closer ties with India, Australia and Japan, though results were mixed. Trade deals were signed, but they rarely matched the scale of EU markets.
The Agonies and Ecstasies: This is best understood in the balance sheet of achievements and failures. On the achievement side, Britain regained regulatory autonomy – from fisheries to financial regulations. It signed trade deals with Australia, Japan and India, showcasing independent diplomacy. For many, Brexit fulfilled a psychological need to reclaim national pride for the United Kingdom. On the failure side, economic costs were undeniable: slower growth, reduced investment and diminished financial power. Britain no longer shaped EU policy, weakening its leverage in Europe. Immigration controls did not deliver the prosperity promised that was expected and sovereignty only meant isolation. Some outcomes were mixed. Immigration controls reduced inflows but created gaps in essential sectors. Sovereignty was gained but at the cost of isolation. Brexit united some in pride but left the society deeply polarised.
When Britain Looks Back, EU Looks Forward: From Britain’s point of view, Brexit created a political environment of permanent turbulence. Governing post-Brexit Britain required balancing sovereignty with harsh economic reality. The Conservative Party was perpetually divided. Public patience wore thin, for promised benefits of Brexit failed to materialise quickly. The short stints at No. 10 were largely because of Brexit in the early years but later compounded by other crises and leadership misjudgements. The revolving door of Prime Ministers became a symbol of a nation struggling to reconcile the promises of Brexit with its realities. Ten years on, today, Brexit is remembered not only for its economic and geopolitical consequences but also for the political instability it unleashed. The agonies and ecstasies of Brexit are mirrored in the agonies and ecstasies of the country’s leadership. Simply put, Britain gained sovereignty but lost stability. It reclaimed pride but endured turbulence. It sought independence but found itself less influential. The legacy of Brexit is not a simple verdict but a paradoxical narrative, one that continues to shape Britain’s destiny even today. As the nation reflects on this anniversary, it must confront the reality that momentous decisions rarely deliver simple outcomes. They leave legacies – contested, paradoxical and enduring. Ten years after Brexit, the clearest conclusion is that it has delivered more disruption than renewal: the UK confronts a world of weaker trade, softer investment and slower growth than many supporters had promised. Politically, it reshaped British public life, but the economic and institutional costs have continued to accumulate, making Brexit less a finished product than an ongoing national readjustment. A decade on, Brexit stands as a defining but divisive moment in modern British history – one that restored formal sovereignty, but at the cost of economic friction, political instability, and a still-unresolved debate over Britain’s future. Today, Brexit remains less a settled chapter than a national reckoning – a moment of rupture that promised restoration, but instead left Britain grappling with economic drag, political turbulence, and the enduring question of what it truly gained by walking away.
The Verdict: Ten years on, the result is a mixed bag and is paradoxical. Brexit achieved sovereignty but at an enormous economic cost. It restored pride but fractured the society. It gave Britain freedom to chart its course but left it less influential in Europe. For the EU, Brexit was a cautionary tale that reinforced cohesion. For Britain, it was a momentous decision whose consequences are still unfolding. Brexit thus is neither a triumph nor a disaster – it is both. Its agonies and ecstasies define a nation still searching for its rightful place in the world. United Kingdom that helped create a nation for itself found itself looking for an identity! Brexit was the offspring of a fond imperial dream – a dream of a Britain that once imagined itself ruling the world, though in truth it never possessed an empire in the classical sense. It was a nostalgia for dominion without acknowledging its own fragmented reality of influence, a yearning for sovereignty that mistook memory for fact.
Thank You.
