Congress MP Dr. Shashi Tharoor on Monday, 6 July 2026 published a sweeping review of Brexit marking exactly a decade since British voters chose to end the United Kingdom's 43-year membership of the European Union, arguing the exercise yielded few gains and significant losses. Writing in an Indian English-language daily, Tharoor questioned whether the hollow bravado over a reassertion of sovereignty has now given way to widespread 'Bregret' — a portmanteau capturing public remorse over the decision.

Context

The Brexit referendum was held on 23 June 2016, when 51.9 per cent of British voters chose to leave the EU in a result that shocked global markets and redrew the political map of Europe. The UK had been a member of the European Economic Community — the EU's predecessor — since 1 January 1973, making its membership span precisely 43 years at the time of the vote. The formal withdrawal was completed on 31 January 2020, and the EU-UK Trade and Cooperation Agreement entered into force on 1 May 2021 to govern post-departure economic ties.

Tharoor, a former UN Under-Secretary-General and former Union Minister of State for External Affairs, has long been among the most prominent Indian voices on global affairs. His commentary on Brexit carries the weight of someone who spent years in multilateral diplomacy and has watched European integration from close quarters.

Policy Backdrop

The central promise of the Leave campaign was the recovery of sovereign decision-making — over borders, laws, and trade — from Brussels. Proponents argued the UK would be free to strike faster, better bilateral trade deals with partners including India, the United States, and Commonwealth nations. In the decade since, that promise has been tested against the hard arithmetic of trade friction, supply-chain disruption, and reduced labour mobility with EU member states.

The EU-UK Trade and Cooperation Agreement, while averting a no-deal cliff edge, introduced new customs checks, regulatory divergence costs, and barriers to services trade that did not exist when the UK was inside the single market. Northern Ireland arrangements have remained a persistent political flashpoint, requiring successive rounds of negotiation between London and Brussels. Tharoor's framing — 'few gains, plenty of losses' — maps closely onto the analytical consensus that has emerged from economic institutions tracking post-Brexit outcomes.

Stakeholders and Impact

UK businesses, particularly exporters of goods and financial services, have borne the most direct costs of regulatory divergence and new border procedures. British exporters to EU markets have faced additional paperwork, rules-of-origin requirements, and, in some sectors, outright market-access restrictions that were absent before departure. For India, Brexit has created a distinct bilateral dynamic: fresh trade negotiations with a post-Brexit UK have proceeded separately from any engagement with Brussels, offering both opportunities and complexities for Indian exporters and investors.

Public opinion within the UK has shifted noticeably since 2016. Polling over the past several years has consistently shown that a majority of British respondents, when asked, say Brexit was the wrong decision — the sentiment Tharoor labels 'Bregret'. That shift has fuelled debate about the long-term trajectory of UK-EU relations, including whether closer alignment or even re-engagement with EU structures is politically feasible.

What's Next

The tenth anniversary of the referendum is likely to intensify domestic UK debate about reviewing or renegotiating elements of the Trade and Cooperation Agreement, particularly on services, youth mobility, and regulatory equivalence. Scheduled EU-UK summits and any adjustments to Northern Ireland arrangements will be closely watched as indicators of whether the relationship is stabilising or drifting further. Tharoor's intervention from India underscores that Brexit continues to be viewed internationally not merely as a British domestic matter, but as a cautionary study in the costs of dismantling deep regional economic integration in the name of sovereignty.
